Constituency profile
Lewes is a rural constituency in East Sussex. It is named after the town of Lewes, although its largest town is Seaford which has a population of around 24,000. Other settlements in the constituency include the towns of Newhaven and Polegate and the villages of Willingdon, Stone Cross, Ringmer and Ditchling. Lewes is a traditional market town known for its 11th-century castle, Seaford is a seaside resort town and Newhaven is an important local port and ferry terminal with regular services to Dieppe in France. The constituency's towns are well-connected by rail to nearby Brighton and Eastbourne. The constituency has average levels of wealth; there is some deprivation in Newhaven whilst the rural parts of the constituency are generally affluent. On average, house prices are lower than the rest of South East England but higher than the national average.
The constituency has a large retired population giving it a high average age. Residents have high rates of homeownership and average levels of education, income and professional employment. The rate of child poverty is low and few residents claim unemployment benefits. A high proportion of residents work in the public sector. White people made up 95% of the population at the 2021 census. At the local council level, the coastal towns and the inland areas west of Lewes are mostly represented by Liberal Democrats, Lewes and the rural areas to its east elected Green Party councillors and the settlements just north of Eastbourne elected Conservatives and independents. An estimated 52% of voters in the constituency supported remaining in the European Union in the 2016 referendum, above the nationwide figure of 48%.
History
The constituency of Lewes has existed since commoners were first summoned to Parliament in 1295, the Model Parliament. This is the county town, though less significant in population today, far surpassed by the City of Brighton and Hove – it has nonetheless been continuously represented since that date.
Until 1885, Lewes was a Parliamentary Borough; until 1868, it was represented by two MPs in the House of Common. This was reduced to one by the Reform Act 1867. Under the Redistribution of Seats Act 1885, the seat was converted to a division of the county of Sussex.
From 1874 until 1997, the constituency's electorate returned only Conservative MPs. In the 1997 general election, the seat was won by Norman Baker for the Liberal Democrats. He retained the seat at the subsequent three elections until he was defeated at the 2015 general election by the Conservative's Maria Caulfield. She won again in 2017 and 2019, but was defeated at the 2024 general election by James MacCleary of the Liberal Democrats.
