Suffolk Coastal

Constituency profile

Suffolk Coastal is a constituency in Suffolk in the East of England. Its largest town is Felixstowe, which has a population of around 25,000. Other settlements include the towns of Woodbridge, Aldeburgh, Saxmundham, Leiston and Southwold and the villages of Trimley St Mary, Martlesham and Rendlesham.

This is a large, rural constituency along Suffolk's North Sea coast with many small market towns and villages. Felixstowe is a port town that was traditionally a small settlement until the opening of the Port of Felixstowe in 1875. This is the UK's largest container port and handles nearly half of the country's containerised trade. Woodbridge is also traditionally a port town with a history of boatbuilding and ropemaking. Aldeburgh and Southwold are small coastal towns, popular with tourists. The Sizewell nuclear power stations are located close to Leiston and are significant local employers. Woodbridge and its nearby villages are mostly affluent whilst Felixstowe and the rest of the constituency have average levels of wealth. House prices across the constituency are generally similar to the rest of the East of England and higher than the UK average.

Suffolk Coastal has low proportions of young and middle-aged adults and a large retired population; in 2024, 31% of residents were over the age of 65. Residents have average levels of income, child poverty and education and the homeownership rate is high. A high proportion of residents work in the transport, tourism and agriculture sectors, and the percentage claiming unemployment benefits is low. White people made up 96% of the population at the 2021 census.

At the local district council, the centre of Felixstowe is represented by the Labour Party, the town's suburbs, nearby villages and the Southwold area by Liberal Democrats, and Leiston and Aldeburgh by Green Party councillors. At the county council, which held elections more recently (in 2026), most seats in the constituency were won by Reform UK. An estimated 54% of voters in Suffolk Coastal supported leaving the European Union in the 2016 referendum, marginally higher than the UK-wide figure of 52%.

History

This East Anglian constituency was created for the 1983 general election from eastern parts of the abolished county constituencies of Eye, and Sudbury and Woodbridge, including the towns of Felixstowe and Woodbridge. Its initial boundaries were coterminous with the recently created District of Suffolk Coastal.

The current constituency area includes three former borough constituencies which sent their own MPs to Parliament until abolished as 'rotten boroughs' by the Reform Act 1832 – Aldeburgh, Dunwich and Orford.

The seat was held from its creation until the 2010 election by the Conservative John Gummer who had previously represented the former seat of Eye from 1979. He was the Secretary of State for the Environment for four years during the second Major ministry and before that was for four years the Minister of State for Agriculture, Fisheries and Food. He stood down in 2010 and was elevated to the House of Lords as Lord Deben.

The MP between 2010 and 2024 was Conservative Thérèse Coffey, who served in the Sunak ministry as the Secretary of State for Environment, Food and Rural Affairs. She also previously served as Secretary of State for Work and Pensions between 2019 and 2022, and as the Deputy Prime Minister and Secretary of State for Health and Social Care during the short-lived Truss ministry from September to October 2022.

However, the Conservatives would lose the seat in the 2024 general election, with Labour's Jenny Riddell-Carpenter being voted in as the MP, with a majority of just over 1,000.
