Brighton Pavilion (UK Parliament constituency)

The Brighton Pavilion constituency is located in East Sussex on England's south coast. It includes the city centre of Brighton and the suburban areas to its north, including Patcham, Hollingdean and Coldean. The constituency is named after the Royal Pavilion, a royal residence built for the future King George IV located within the constituency. Brighton is a popular seaside resort and the Brighton Pavilion constituency contains the highest proportion of lesbian, gay or bisexual residents (11.9%) of any constituency in England and Wales.^[4]

Compared to national averages, residents are considerably younger and less religious and have high levels of education and professional employment. House prices and household income are generally higher than average,^[5] although there are some areas of high deprivation like Hollingdean,^[6] which has a large amount of social housing. The ethnic makeup of the constituency is similar to the country as a whole, with White people forming 85% of the population.^[5]

Local politics are mixed; at the city council, residents in city centre wards are represented by Green Party councillors, the more deprived areas around Hollingdean elected Labour Party councillors and Conservatives represent the outskirts near Patcham. In the 2016 referendum on European Union membership, voters in the constituency overwhelmingly supported remaining in the European Union with an estimated 83% voting for this option. This made Brighton Pavilion the second-most remain-supporting constituency in the United Kingdom.^[5]

The constituency was created in 1950 from the former two-member constituency of Brighton (one of the last remaining multi-member constituencies), for which Brighton Pavilion's first Member of Parliament, Sir William Teeling, had previously been the joint representative.

From 1950 to 1997, the seat elected Conservative MPs. In 1997, David Lepper of the Labour Party, aided by somewhat notionally favourable minor boundary changes before the 1997 general election, began service as MP for thirteen years by winning the two subsequent elections. The Conservatives' share of the vote has declined at every election there since 1979.

In July 2007, the Green Party selected Caroline Lucas to contest the seat, at which point she was a Member of the European Parliament for the South East England constituency.^[13] In November 2009, Charlotte Vere was selected as the Conservative Party candidate at an open primary attended by local Conservative Party members and residents.^[14] In January 2010, the Liberal Democrats also selected a female candidate, Bernadette Millam.^[15] Labour had selected Nancy Platts, a local campaigner and former union worker, as their candidate in June 2007.^[16] This meant that, distinctively, all of the four leading parties in the constituency had female candidates. In 2010, Labour's share of the vote fell by 6.5%, and Lucas, then leading the Green Party, won the seat. In contrast to national results, the Conservative and Liberal Democrat share of the vote fell.^[17]

Lucas retained the seat for the Green Party at the 2015 general election with an increased majority. Purna Sen, who held senior roles at the Commonwealth, LSE, and Amnesty International, was selected to contest the seat for Labour. Clarence Mitchell, a former BBC News reporter and spokesman for the family of Madeleine McCann, was selected as the Conservative Party candidate.^[18]

For the 2017 general election and the 2019 general election, the local Liberal Democrat party chose not to field a candidate in the seat, endorsing Lucas instead due to their shared pro-EU stance.^[19] Lucas retained Brighton Pavilion for the Green Party, which was returned with the biggest numerical majority for any candidate in the seat since 1959. In the 2019 election, the seat had the largest winning margin and the highest winning vote share of any seat not held by the Conservatives or Labour.^{[citation needed]} Lucas announced on 8 June 2023, that she would not be standing in the subsequent UK general election.^[20] On 19 July 2023, the Green Party picked Siân Berry to replace her.^[21] Berry was elected as the MP for Brighton Pavilion at the 2024 election with a slightly reduced majority of 27%.
