In the Bundestag, 2005–2019
In 2005, Ursula von der Leyen was appointed Federal Minister of Family Affairs and Youth in the cabinet of Angela Merkel. On the 60th anniversary of the founding of Israel, von der Leyen participated in the first joint cabinet meeting of the governments of Germany and Israel in Jerusalem in March 2008.
At the federal election of 2009, von der Leyen was elected to the Bundestag, Germany's Parliament, representing the 42nd electoral district of Hanover, alongside Edelgard Bulmahn of the Social Democrats. In the negotiations to form a coalition government following the elections, she led the CDU/CSU delegation in the working group on health policy; her co-chair from the FDP was Philipp Rösler. She was reappointed as family minister, but on 30 November 2009 succeeded Franz Josef Jung as Federal Minister of Labour and Social Affairs.
During her time in office, von der Leyen cultivated the image of being the social conscience of the CDU and helped Merkel to move the CDU into the political centre-ground. In speaking out for increasing the number of childcare nurseries, for the introduction of a women's quota for listed companies' main boards, for gay marriage and a nationwide minimum wage, von der Leyen made enemies among the more traditionalist party members and won admirers on the left.
Von der Leyen also lobbied for lowering the barriers to immigration for some foreign workers, to fight shortages of skilled workers in Germany. In 2013, she concluded an agreement with the Government of the Philippines that was aimed at helping Filipino health care professionals to gain employment in Germany. A vital provision of the agreement is that the Filipino workers are to be employed on the same terms and conditions as their German counterparts.
Von der Leyen was initially considered the front-runner to be nominated by the ruling CDU/CSU parties for election as President of Germany in the 2010 presidential election, but Christian Wulff was eventually chosen as the parties' candidate. The news media later reported that Wulff's nomination came as a blow to Merkel, whose choice of von der Leyen had been blocked by the two parties' more conservative state premiers.
In November 2010, von der Leyen was elected (with 85% of the votes) as one of four deputies of CDU chairwoman Merkel, serving alongside Volker Bouffier, Norbert Röttgen and Annette Schavan. Later that month, she told the Bild am Sonntag newspaper that the CDU should consider establishing a formal voting process for choosing future candidates for Chancellor. In 2012, she was re-elected (with 69% of the votes) as one of Merkel's deputies as CDU chairwoman, this time serving alongside Bouffier, Julia Klöckner, Armin Laschet and Thomas Strobl.
In the negotiations to form a government following the 2013 federal elections, von der Leyen led the CDU/CSU delegation in the labour policy working group, with Andrea Nahles of the SPD as her co-chair.
In December 2013, Ursula von der Leyen was appointed by Merkel as Germany's first female defence minister. By placing a significant party figure such as von der Leyen at the head of the Defence Ministry, Merkel was widely seen as reinvigorating the scandal-ridden ministry's morale and prestige. Until her 2019 appointment as the president of the European Commission, she was the only minister to remain with Merkel since she became chancellor in 2005. In December 2014, von der Leyen had her fingerprint cloned by a German hacker who was able to use the commercially available VeriFinger product from Neurotechnology UAB to replicate her fingerprint using photographs taken with a "standard photo camera". In August 2016, von der Leyen joined the World Economic Forum board of trustees. In September 2016, von der Leyen chaired the EPP Defence Ministers Meeting, which gathers EPP defence ministers ahead of meetings of the Council of the European Union. Former British Secretary of State for Defence Michael Fallon noted in 2019 that she had been "a star presence" in the NATO community and "the doyenne of NATO ministers for over five years". She has faced domestic criticism for her leadership style, reliance on outside consultants, and continued gaps in military readiness.
Within her first year in office, von der Leyen visited the Bundeswehr troops stationed in Afghanistan three times and oversaw the gradual withdrawal of German soldiers from the country as NATO was winding down its 13-year combat mission ISAF. In September 2015, she signalled that she was open to delaying the withdrawal of 850 German soldiers from Afghanistan beyond 2016 after the Taliban's surprise seizure of the northern city of Kunduz. German forces had been based in Kunduz as part of NATO-led ISAF and remained stationed in the north of the country. She later opposed the troop withdrawal from Afghanistan.
In the summer of 2014, she was instrumental in Germany's decision to resupply the Kurdish Peshmerga fighters with lethal assistance. Following criticism from German officials of Turkish president Recep Tayyip Erdoğan's escalation of the Kurdish–Turkish conflict in August 2015, von der Leyen decided to let Germany's three-year Patriot missile batteries mission to southern Turkey lapse in January 2016 instead of seeking parliamentary approval to extend it. That same month, she participated in the first joint cabinet meeting of the governments of Germany and Turkey in Berlin. By April 2016, under von der Leyen's leadership, the German Federal Armed Forces announced they would commit 65 million Euro to establish a permanent presence at Incirlik Air Base, as part of Germany's commitment to the military intervention against ISIL.
At the Munich Security Conference in February 2015, von der Leyen publicly defended the German refusal to supply Ukraine with weapons. Stressing that it was necessary to remain united in Europe over Ukraine, she argued that negotiations with Russia, unlike with the Islamic State of Iraq and the Levant jihadists, were possible. Angela Merkel said that she saw Ukraine and Russia as a chance to prove that in the 21st century, developed nations should solve disputes at the negotiating table, not with weapons. She also noted that Russia has an almost infinite supply of weapons it could send to Ukraine. She questioned whether any effort by the West could match that or, more importantly, achieve the outcome sought by Ukraine and its supporters. On the contrary, von der Leyen said that giving the Ukrainians arms to help them defend themselves could have unintended and fateful consequences. "Weapons deliveries would be a fire accelerant", von der Leyen told the Süddeutsche Zeitung daily. She agreed with NATO SACEUR General Philip Breedlove that "it could give the Kremlin the excuse to openly intervene in this conflict".
After Hungary used a water cannon and tear gas to drive asylum seekers back from the Hungarian-Serbian border in September 2015, during the European migrant crisis, von der Leyen publicly criticised the government of Prime Minister Viktor Orbán and called the measures "not acceptable and [...] against the European rules that we have".
Under von der Leyen's leadership, the German parliament approved government plans in early 2016 to send up to 650 soldiers to Mali, boosting its presence in the UK peacekeeping mission MINUSMA in the West African country.
In June 2014, von der Leyen introduced a €100 million plan to make the Bundeswehr more attractive to recruits, including by offering crèches for soldiers' children, limiting postings to match school term dates, and considerable rises in hardship allowances for difficult postings.
In August 2014 in a debate over funding priorities, von der Leyen categorised as "vital to national interests" only sensor and cryptotechnology and left all other funding items as secondary. Economy Minister Sigmar Gabriel was unhappy with her and said that "this will have significant consequences for national defence procurement and European cooperation" as the key focus of the debate would determine where funding will be allocated. She admitted that "Germany would at present be unable to meet NATO requirements". For example, at this time the majority of the German Air Force was grounded, with 42 of its 109 Eurofighter Typhoons and 38 of 89 Tornado fighters ready for deployment. An external report had been commissioned and, with cost overruns rising into the billions of euros, all nine of the Bundeswehr's major projects had been delayed by between 30 and 360 months. This occurred one year into her tenure at Defense.
In 2015, as a result of severe NATO–Russian tensions in Europe, Germany announced an increase in defence spending. In May 2015, the German government approved an increase in defence spending, at the time 1.3% of GDP, by 6.2% over the following five years, allowing the Ministry of Defense to modernise the army fully. Plans were also announced to expand the tank fleet to a potential number of 328, order 131 more Boxer armoured personnel carriers, increase the submarine fleet, and to develop a new fighter jet to replace the Tornado. Germany considered increasing the size of the army, and in May 2016 von der Leyen announced it would spend €130 billion on new equipment by 2030 and add nearly 7,000 soldiers by 2023 in the first German military expansion since the end of the Cold War. In February 2017, she announced that the number of Bundeswehr professional soldiers would increase from 178,000 to 198,000 by 2024.
In April 2017, after Bundeswehr officials failed to properly investigate persistent reports of brutal hazing rituals, sexual humiliation, and bullying in military training, von der Leyen fired the army's training commander, Major General Walter Spindler.
As a consequence of improved Dutch–German cooperation, since 2014 two of the three Royal Netherlands Army Brigades are under German Command. In 2014, the 11th Airmobile Brigade was integrated into the German Division of fast forces (DSK). The German 414 Tank Battalion was integrated into the Dutch 43rd Mechanized Brigade. In turn, the Dutch 43rd Mechanized Brigade will be assigned to the 1st Panzer Division of the German army, with the integration starting at the beginning of 2016, and the unit becoming operational at the end of 2019. In February 2016 it was announced that the Seebatallion of the German Navy would start to operate under Royal Dutch Navy command. The Dutch-German military cooperation was seen in 2016 by von der Leyen and Dutch Minister of Defence Jeanine Hennis-Plasschaert as an example for setting up a European defence union.
A further proposal by von der Leyen, to allow non-German EU nationals to join the Bundeswehr, was met in July 2016 by strong opposition, even from her own party.
According to a policy dictated by von der Leyen in February 2017, the Bundeswehr is to play a greater role as an "anchor army" for smaller NATO states, by improving coordination between its divisions and smaller members' Brigades.
It was announced in February 2017 that the Czech Republic's 4th Rapid Deployment Brigade and Romania's 81st Mechanized Brigade would be integrated into Germany's 10th Armoured Division and Rapid Response Forces Division.
In October 2014, von der Leyen pledged to get a grip on Germany's military equipment budget after publishing a KPMG report on repeated failures in controlling suppliers, costs and delivery deadlines, e.g., with the Airbus A400M Atlas transport plane, Eurofighter Typhoon jet and the Boxer armoured fighting vehicle.
In January 2015, von der Leyen publicly criticised Airbus over delays in the delivery of A400M military transport planes, complaining that the company had a serious problem with product quality. Under her leadership, the ministry agreed to accept 13 million euros in compensation for delays in deliveries of both the second and third A400M aircraft. In 2016, she asked for an additional 12.7 million euros in damages for delays in the delivery of a fourth plane. Also in 2015, von der Leyen chose MBDA, jointly owned by Airbus, Britain's BAE Systems, and Italy's Leonardo S.p.A., to build the Medium Extended Air Defense System, but set strict milestones for it to retain the contract.
During her May 2015 visit to India, von der Leyen expressed support for a project initiated by the Indian government to build six small German TKMS diesel-electric submarines for a total cost of $11 billion.
In 2019, she also promoted the German government's decisions on arms exports to Saudi Arabia and Turkey.
Since 2018 an investigative committee organised by Germany's Federal Audit Office has been looking into how contracts worth tens of millions of euros were awarded to external consultancy firms. The auditing office has found several irregularities in how the contracts were awarded. During the investigation, two of von der Leyen's phones were confiscated, but data from both phones had been deleted before being returned to the defence ministry. In turn, opposition lawmaker Tobias Lindner has filed a criminal complaint against von der Leyen, suspecting deliberate destruction of evidence relevant for the case.
Von der Leyen was elected as a member of the CDU executive board in December 2014 and received 70.5% of the votes. Compared to her re-elections in 2016 (72.4%) and 2018 (57.47%), it was the weakest of all the results.
As a cabinet member, von der Leyen was, for several years, regarded as one of the leading contenders to succeed Merkel as Chancellor. In 2010 she was Merkel's preferred candidate for President of Germany, but her nomination was blocked by the conservative wing of the CDU/CSU. From 2018 until her nomination as European Commission president, she was described as the favourite to succeed Jens Stoltenberg as Secretary General of NATO. Die Welt reported that von der Leyen "is highly respected in the alliance" and that "all the [NATO] defence ministers listen when she speaks".
