Peter Benjamin Mandelson, Baron Mandelson (born 21 October 1953), is a British former Labour Party politician, lobbyist and diplomat. He was the Member of Parliament (MP) for Hartlepool from 1992 to 2004. He served in Tony Blair and Gordon Brown's cabinets as Minister without portfolio, Secretary of State for Northern Ireland, Business Secretary and First Secretary of State. He was the British Ambassador to the United States in 2025 under Prime Minister Keir Starmer.
Mandelson served as the Labour Party's director of communications from 1985 to 1990 during the leadership of Neil Kinnock. Sidelined during John Smith's leadership from 1992 to 1994, Mandelson became close to Blair and Brown. He was widely regarded as one of the architects of New Labour and a key adviser to Blair, contributing to the party's election victories in 1997 and 2001.
Mandelson served as Minister without Portfolio from 1997 to 1998, Secretary of State for Business, Innovation and Skills and President of the Board of Trade in 1998 and again from 2008 to 2010, Secretary of State for Northern Ireland from 1999 to 2001, and First Secretary of State and Lord President of the Council from 2009 to 2010. He was European Commissioner for Trade from 2004 to 2008, being elevated to the House of Lords as a life peer in 2008 to serve in the Brown cabinet as business secretary. After Labour lost the 2010 general election, Mandelson co-founded the lobbying firm Global Counsel. He remained active in Labour politics, and was an adviser to Starmer before Labour's return to office at the 2024 general election. During his tenure as ambassador to the United States, Mandelson focused on promoting trade and fostering relationships with the US government during the second presidency of Donald Trump.
Mandelson's career has been marked by controversy, which resulted in his twice resigning from the Cabinet and being dismissed as ambassador in 2025. He bought a home in 1996 partly with an interest-free loan of £373,000 from Geoffrey Robinson, a Cabinet colleague whose business dealings were subject to an inquiry by Mandelson's department. He had not declared the loan in the Register of Members' Interests and resigned in December 1998. In January 2001, he again resigned from the government following accusations of using his position to influence a passport application for S. P. Hinduja.
In September 2025, a scandal arose concerning Mandelson's association with the financier and convicted child sex offender Jeffrey Epstein, which had been reported in 2019. Following reports that Mandelson had continued the friendship following Epstein's 2008 conviction, he was dismissed as ambassador by Starmer. In February 2026, further reports alleged that Mandelson and his husband had received payments from Epstein, and that in 2009 and 2010 Mandelson had passed sensitive government information to Epstein. Mandelson subsequently resigned from the Labour Party and from the House of Lords, and the Metropolitan Police opened an investigation into the allegations. He was later arrested on suspicion of misconduct in public office, then released on bail pending further investigation. In April 2026, it was reported that UKSV had recommended against granting Mandelson security clearance in January 2025, but that officials in the Foreign, Commonwealth and Development Office overruled the recommendation and granted clearance anyway. A government spokesperson said the decision was taken by FCDO officials, and that Prime Minister Sir Keir Starmer was not aware of the override until April 2026.

Early life and education
Peter Benjamin Mandelson was born on 21 October 1953, in Hendon, Middlesex, the younger son of George Norman ("Tony") Mandelson and Mary Joyce. His father George was advertising manager of The Jewish Chronicle and an officer in the Royal Dragoons during the Second World War. His mother Mary was the daughter of Herbert Morrison and his first wife, Margaret Kent. Morrison was a London County Council leader, a member of the War Cabinet as Home Secretary and subsequently a cabinet minister in the Attlee government.
Of Polish Jewish ancestry, Mandelson's grandfather, Norman Mandelson, founded the Harrow United Synagogue. Mandelson was raised in Hampstead Garden Suburb; recalling his childhood, he said "my whole upbringing was framed around the Suburb – my friendships and values."
Mandelson attended the Garden Suburb School, and from 1965 to 1972 Hendon County Grammar School. During his teenage years he joined the Young Communist League due to the UK's support of the United States' role in the Vietnam War. From 1973 to 1976
he read philosophy, politics and economics (PPE) at the University of Oxford where he was a student at St Catherine's College, and his tutors included Nicholas Stern.
Early career
Mandelson worked in the Economic Department of the Trades Union Congress between 1977 and 1978; from 1978 to 1980, he was Chairman of the British Youth Council. In 1978, he was delegated to attend the Soviet-organised World Festival of Youth and Students at Havana, Cuba. He was elected to Lambeth Council at a by-election in 1979 but stood down in 1982, disillusioned with the state of Labour politics during the leadership of Michael Foot. Mandelson then worked from 1982 to 1985 as a television producer at London Weekend Television on Weekend World, where he formed a friendship with his superior John Birt.
Political career
Director of communications
In 1985, the Labour Party leader Neil Kinnock appointed Mandelson as the party's director of communications. As director, he was one of the first people in Britain to whom the term "spin doctor" was applied, and he was nicknamed the "Prince of Darkness". Mandelson ran the campaign at the 1986 Fulham by-election where Labour defeated the Conservative Party.
For the 1987 general election campaign, Mandelson commissioned the film director Hugh Hudson, whose Chariots of Fire (1981) had won an Oscar as Best Picture, to make a party political broadcast promoting Kinnock as a potential prime minister. Tagged "Kinnock – the Movie", it led to the party leader's approval rating being raised by 16%, to 19%, in polls, and was even repeated in another party political broadcast slot. The election, held on 11 June 1987, returned Margaret Thatcher's Conservatives for the third time, although Labour gained 20 seats, and, this time, convincingly pushed the SDP–Liberal Alliance into third place. Opponents termed the Labour Party's election campaign "a brilliantly successful election defeat". He ceased being a Labour Party official in 1990 when he was selected as Labour candidate for the constituency of Hartlepool, which was then considered a safe seat.
Member of Parliament
Mandelson was first elected to the House of Commons at the 1992 general election which John Major's Conservatives won, and made several speeches outlining his strong support for the European Union. Although sidelined during the brief period when John Smith led the Labour Party, Mandelson was by now close to two shadow cabinet members – Gordon Brown and Tony Blair – each regarded as potential future party leaders. Following Smith's sudden death on 12 May 1994, Mandelson opted to back Blair for the leadership, believing him a superior communicator to Brown, and played a leading role in the leadership campaign. This created acrimony between Mandelson and Brown, though they were considered to be allies in the Labour Party.
In 1994, Kate Garvey suggested that Mandelson (who was at the time being derided by the trades unions and other Labour factions), should adopt a nom de guerre throughout Blair's leadership bid, so that he might conceal his considerable role within the campaign team. Mandelson agreed to be called "Bobby" for the duration and was thanked by Blair using this pseudonym in his victory speech. After becoming a close ally and trusted adviser to Blair, Mandelson was Opposition spokesman on the Civil Service from 1995 to 1997, and was Labour's election campaign director for the 1997 general election, which Labour won decisively. He also won re-election in 2001.
During the 2009 expenses scandal, The Daily Telegraph raised questions about the timing of Mandelson's second home allowance claim, dating from 2004, saying, "Lord Mandelson billed the taxpayer for almost £3,000 of work on his constituency home in Hartlepool less than a week after announcing his decision to stand down as an MP." Mandelson said in a statement, "The work done was necessary maintenance. All claims made were reasonable and submitted consistent with parliamentary rules."
Minister without Portfolio
Mandelson served as a Minister without Portfolio in the Cabinet Office from May 1997 to July 1998, when his job was to co-ordinate government from outside the cabinet. A few months after his appointment, he also acquired responsibility for the Millennium Dome, after Blair decided to go ahead with the project despite the opposition of most of the Cabinet and in the face of media hostility. Jennie Page, the Dome project's chief executive, resigned in February 2000 after a chaotic opening night and disappointing attendance figures. In June 2000, in what was seen as a reference to the close interest in the Dome from Mandelson, known at the time as so-called "Dome Secretary" and his successor Charlie Falconer, Baron Falconer of Thoroton, Page told the House of Commons Select Committee for Culture and Heritage: "I made several attempts to persuade ministers that standing back from the Dome would be good for them as well as good for the Dome".
Secretary of State for Trade and Industry
In July 1998, Mandelson was appointed to the Cabinet as Secretary of State for Trade and Industry and was sworn of the Privy Council; he launched the Millennium Bug And Electronic Commerce Bill and a Competitiveness White paper, which he described, as "bold, far reaching and absolutely necessary". He also appointed a "Net Tsar" to lead the UK in what he termed the "new industrial revolution". Mandelson reportedly urged Blair to proceed with the Post Office's Horizon IT system, leading to the British Post Office scandal in which thousands of innocent subpostmasters were wrongfully convicted of theft, fraud and false accounting.
Mandelson was a friend of Labour MP and aerospace CEO Geoffrey Robinson since 1979 when he was a researcher to Labour MP Albert Booth. Mandelson had previously been financially supported by Robinson while working with trade unions, and had remained in touch with him intermittently. Robinson stated that in 1994 Mandelson wrote to Brown, offering his services and stating to Brown he should not seek leadership of what would become New Labour, and in so doing gravitated towards Tony Blair, causing a rift (also referred to as a "feud" by The Guardian) between Brown and Mandelson.
Mandelson bought a home in an exclusive area of Notting Hill in October 1996 partly with an interest-free unsecured personal loan of £373,000 (£753,144 adjusted for inflation in 2025) from Robinson, whose business dealings were later subject to an inquiry by Mandelson's department. The total value of the home was £475,000 (£959,097 adjusted for inflation in 2025).
In 1996, Mandelson was at a dinner at Robinson's flat, where he discussed difficulties with calls from Tony Blair at early hours, and also in a cri de coeur complained to Robinson that he was miserable in his small flat in Wilmington Square, and about his financial circumstances due to his "modest" salary in New Labour, complaining that he did not have "a flat in which he could relax and entertain his friends". Following this, Robinson queried his intentions: I asked what he had in mind. He said "Oh there is a place in Notting Hill I would really like, but it's too expensive and there is no-one to help me!" At this point I said that financially I was in a good position and that I might be able to assist if he wanted me to. ...
My interpretation of his remark was and remains that he was looking for a loan. I would not say that is why he had come to dinner. But, to judge from the alacrity with which he responded, I do not think I misinterpreted what he said.
Secretary of State for Northern Ireland
Mandelson was out of the Cabinet for ten months. In October 1999 he was appointed Secretary of State for Northern Ireland, replacing Mo Mowlam. In his first speech in the post he mistakenly referred to himself as the "Secretary of State for Ireland". During his tenure he oversaw the creation of the devolved legislative assembly and power-sharing executive and reform of the Police Service of Northern Ireland.
On 24 January 2001, Mandelson resigned from the Government for a second time, following accusations of using his position to influence a passport application, stating "I would only ask people to understand that my sole desire and motivation throughout was to emphasise that I had not sought to influence the decision on naturalisation in any way at all, merely to pass on a request for information and the prime minister is entirely satisfied with this." He had contacted Home Office Minister Mike O'Brien on behalf of Srichand Hinduja, an Indian businessman who was seeking British citizenship and whose family firm was to become the main sponsor of the "Faith Zone" in the Millennium Dome. At the time Hinduja and his brothers were under investigation by the Indian Government for alleged involvement in the Bofors scandal. Mandelson insisted he had done nothing wrong and was exonerated by an independent inquiry by Sir Anthony Hammond, which concluded that neither Mandelson nor anyone else had acted improperly.
At the 2001 general election Mandelson was challenged by Arthur Scargill of the Socialist Labour Party and by John Booth, a former Labour Party press officer standing as "Genuine Labour", but Mandelson was re-elected with a large majority. In his victory speech, Mandelson said: "It was said that I was facing political oblivion ... Well, they underestimated Hartlepool and they underestimated me because I am a fighter and not a quitter." His quote would later be referenced by Liz Truss towards the end of her notably short tenure as prime minister in October 2022.
Stepping down as MP
Despite Labour's victory at the June 2001 general election, a third Cabinet appointment did not materialise and Mandelson indicated his interest in becoming the United Kingdom's European commissioner when the new Commission was established in 2004. Both of Britain's Commissioners, Neil Kinnock and Chris Patten, were due to stand down. Appointment as a European Commissioner would require his resignation from Parliament, precipitating a by-election in his Hartlepool constituency. His EC appointment was announced in the summer and on 8 September 2004 Mandelson resigned his seat by petitioning to become Steward of the Manor of Northstead. Labour held the seat at the 2004 Hartlepool by-election with a much-reduced majority of 2,033 votes (equating to 40.7% of the vote), being succeeded by Iain Wright as MP for Hartlepool.
European Commissioner
On 22 November 2004, Mandelson became Britain's European Commissioner, taking the trade portfolio. During the summer of 2008, Mandelson had a widely publicised disagreement with Nicolas Sarkozy, President of France. Sarkozy accused him of trying to sell out European farmers and appeared to blame his handling of the Doha round of trade talks for the "no" vote in the Irish referendum on the Treaty of Lisbon. Mandelson said his position at world trade talks had been undermined and told the BBC he did not start the row, saying, "I stood up for myself, I'm not to be bullied", and said he believed the row was over but renewed his warnings on protectionism. In October 2008, he left his post as Trade Commissioner to return to British politics.
The release of the Epstein files in 2026 indicated that Jeffrey Epstein made payments totaling approximately £55,000 to Mandelson or his partner between 2003 and 2004, and also covered educational fees for Mandelson's husband, Reinaldo Avila da Silva. Emails within the files suggested that Mandelson shared sensitive UK government information with Epstein during the aftermath of the 2008 financial crisis, including early notice of a €500 billion EU bank bailout and lobbying efforts regarding a proposed 50% "super tax" on bankers' bonuses. The revelations prompted reactions from former Prime Minister Gordon Brown, who had appointed Mandelson to ministerial positions and the House of Lords, expressing regret over the appointments, and providing evidence to the Metropolitan Police for further inquiry. Amid growing public and political scrutiny, Mandelson resigned from the Labour Party and stepped down from the House of Lords in early February 2026, while a criminal investigation into potential misconduct in public office was started, following which he was arrested.
On 22 April 2005, The Times reported that Mandelson had spent the previous New Year's Eve on the yacht of Paul Allen, the co-founder of Microsoft, a company that was at the centre of a major EU investigation. In 2006, The Daily Mail reported that Mandelson had received a free cruise on a yacht from Diego Della Valle, a controversial Italian mogul, raising questions as Della Valle's businesses (such as luxury shoe brand Tod's) benefited from tariffs imposed shortly thereafter by Mandelson as EU Trade Commissioner on Chinese shoes. In October 2008, Mandelson was the subject of much press speculation when it was reported that British-born Canadian financier Nathaniel Rothschild, 5th Baron Rothschild and the Russian oligarch Oleg Deripaska had met Mandelson when staying on a yacht moored near Corfu, in order to attend a party held by Rothschild. After speculation that this might constitute a conflict of interest for Mandelson, Rothschild wrote a letter to The Times newspaper alleging that another guest was Conservative Shadow Chancellor of the Exchequer George Osborne, who, he said, illicitly tried to solicit a donation from the Russian for his party.
Peerage and return to Cabinet
On 3 October 2008, as part of Gordon Brown's Cabinet reshuffle it was announced, amid some controversy and surprise, that Mandelson would return to Government in the re-designated post of Business Secretary and would be raised to the peerage, thus becoming a member of the House of Lords. His return surprised many due to his long-standing political rivalry with Brown. On 13 October 2008 he was created Baron Mandelson, of Foy in the County of Herefordshire and of Hartlepool in the County of Durham, being introduced in the House of Lords the same day. Following his return to office, Mandelson supported the planned Heathrow expansion. On 6 March 2009, environmental protester Leila Deen of anti-aviation group Plane Stupid approached him outside a summit on the government's low-carbon industrial strategy and threw a cup of green custard in his face in protest over his support for a third runway at Heathrow Airport. The protester was cautioned on 9 April for causing "harassment, alarm or distress".
In a Cabinet reshuffle on 5 June 2009 Mandelson was appointed Lord President of the Council with the honorary title of First Secretary of State; it was also announced that the Department for Innovation, Universities and Skills would be merged into his, affording him the new title of Secretary of State for Business, Innovation and Skills and that he would continue as President of the Board of Trade. Mandelson was a member of 35 of the 43 Cabinet committees and subcommittees.
In August 2009, Mandelson was widely reported to have ordered "technical measures" such as internet disconnection to be included in the draft of the Digital Economy Act 2010 after a "big lobbying operation", even though the Digital Britain report had rejected this type of punishment. The Independent reported that according to their Whitehall sources, Mandelson was persuaded that tough laws were needed to reduce online copyright infringement following an intensive lobbying campaign by influential people in the music and film industry. The paper also reported that this included a meeting with DreamWorks co-founder David Geffen at the Rothschild family villa on the Greek island of Corfu. Mandelson's spokesperson claimed that there had been no discussion of internet piracy during the Corfu dinner and suggested that the decision to reverse Lord Carter's findings had been taken in late July before the trip. The Times reported after the Corfu meeting that an unnamed Whitehall source had confirmed that before this trip, Mandelson had shown little personal interest in the Digital Britain agenda, which has been ongoing for several years. According to the source of The Times, Mandelson returned from holiday and effectively issued an edict that the regulation needed to be tougher.
Post-Cabinet
In November 2010, Mandelson and Benjamin Wegg-Prosser founded Global Counsel, a London-based lobbying firm with the financial support of WPP, the advertising giant. The firm provides advice for corporate strategists and senior management worldwide. The firm was valued at about GBP 30 million when the Messina Group run by Jim Messina bought a 20 percent stake in 2024.
Lord Mandelson has been criticised for not revealing his clientele. As a corporate lobbyist, he personally helped clients such as Shein, Shell, Palantir, Alibaba, TikTok, and the UK private water industry obtain meetings with ministers and senior officials.
In May 2012, Mandelson confirmed that he was advising Asia Pulp & Paper (APP) in selling timber products to Europe. In that year, APP was accused of illegal logging in Indonesia and damaging the habitats of rare animals such as the Sumatran tiger. At least 67 companies worldwide, such as Tesco and Kraft Foods since 2004 and Danone since 2012, have boycotted APP. In April 2014, it was reported that Mandelson had strong ties to Russian conglomerate Sistema. Mandelson was criticised for being a member of the House of Lords while running a lobbying firm. In 2021, he was the only Labour peer to vote against an amendment denouncing the alleged human right violation in Xinjiang. Mandelson served as a senior adviser to the investment bank Lazard from January 2011 until March 2022. In 2013, Mandelson also joined the Board of Trustees of Deutsche Bank's Alfred Herrhausen Gesellschaft.
After Labour lost the 2010 general election and the Conservative–Liberal Democrat coalition was formed, Mandelson's memoirs, The Third Man: Life at the Heart of New Labour, were published in July 2010. The memoirs were criticised by Labour leadership contenders Ed and David Miliband, and by Andy Burnham. During this time, Mandelson was appointed president of the international think tank Policy Network. In 1999, 2008, 2009, 2011, 2012, 2013, and 2014, Mandelson was an invited guest of the Bilderberg Group and attended the annual conferences. In May 2011, there was speculation that Mandelson had been approached by China to be a candidate for the leadership of the International Monetary Fund, even though he had not served as a finance minister or headed a central bank. It was then speculated in March 2012 that Mandelson's name might be put forward to succeed Pascal Lamy as Director-General of the World Trade Organization, backed by David Cameron. In June 2013, writing for the Progress website, Mandelson warned Labour it risked harming its election chances if affiliated trade unions continued to "manipulate parliamentary selections" as was alleged in the 2013 Labour Party Falkirk candidate selection controversy.
Personal life
Mandelson is gay and in the late 1990s was said to be "intensely private" about his personal life. Mandelson married Reinaldo Avila da Silva, a Brazilian translator, on 28 October 2023, after having lived in London with him since March 1998. The pair met in the Caribbean in the mid '90s when Mandelson was an MP and da Silva was an international student in London. The couple have a collie dog named Jock.
In 2008 Mandelson was hospitalised, suffering from kidney stone disease, shortly after drinking a glass of Chinese yoghurt in front of reporters in order to show his confidence in Chinese dairy products, which were being banned in Europe due to a concern over deliberate addition of melamine. The melamine was added to make otherwise diluted milk appear as though it had the correct amount of protein, but had caused ailments - including deaths - in Chinese children. Though his own condition was unrelated to melamine in dairy products, the media reported on the connection. Mandelson was guest of honour in 2011 at Herbert Morrison Primary School in Vauxhall, South London, which was hosting a special themed day in honour of Mandelson's grandfather, Herbert Morrison, after whom the school was named.
Attempted outings and harassment
While his sexual orientation was known to friends, colleagues and constituents, in 1987 the News of the World ran an issue that attempted to out Mandelson as gay. Mandelson did not respond. Mandelson was outed again by Matthew Parris in 1998 on the BBC programme Newsnight. This led to press harassment of his partner, with the Daily Express sending a reporter to take pictures of him while he was at his languages course. An internal investigation later found that the photos had been obtained without Avila da Silva's consent and images of him attempting to cover his face had been secretly deleted. Mandelson phoned the BBC and the Press Complaints Commission following Newsnight's broadcast, and an internal memo was later sent within the BBC, stating: "under no circumstances whatsoever should allegations about the private life of Peter Mandelson be repeated or referred to on any broadcast."
Urination incident
In April 2026, months after his sacking from Starmer's cabinet, Mandelson faced a fixed penalty notice of £300 for urinating in public. Mandelson was photographed urinating while standing outside the home of former chancellor George Osborne in November 2025. The Royal Borough of Kensington and Chelsea intended to fine Mandelson, yet had not issued the fine because they had "struggled to find his address." Mandelson later blamed his actions on being stood up by an Uber driver when he was "bursting for a pee", and expressed embarrassment over the incident.
Rescinded honorary roles
Mandelson served until 8 October 2008 as President of the Central School of Speech and Drama. In 2013, he was appointed to the revived post of High Steward of Hull, an ancient ceremonial position held by his grandfather in 1956–65 and defunct since 1974. In September 2025, following the Epstein revelations, he was stripped of the role.
Mandelson served as Chancellor of Manchester Metropolitan University from 2016 to 2024. In September 2025, following the Epstein revelations, the university rescinded his honorary doctorate and commemorative medal.
Mandelson contested the 2024 University of Oxford Chancellor election, which William Hague won; Mandelson finished fourth out of thirty-eight candidates. It was later reported that Mandelson had lobbied numerous Labour government ministers in an attempt to secure the role.
Mandelson was appointed as an honorary fellow of his alma mater, St Catherine's College, Oxford in April 2018. In November 2025, following the Epstein revelations, he resigned.
In the media
BBC Four's Storyville (2010), Mandelson: The Real PM?, directed by Hannah Rothschild, is a fly-on-the-wall documentary about Mandelson as business secretary in the run up to the 2010 general election.
Mandelson was portrayed by Paul Rhys in the 2003 Channel 4 drama The Deal.
Mandelson was portrayed by Mark Gatiss in the 2015 Channel 4 drama Coalition.
Mandelson was portrayed by Nigel Planer in the 2011 comedy drama The Hunt for Tony Blair.
