Further to the 2023 Periodic Review of Westminster constituencies, enacted by the Parliamentary Constituencies Order 2023, from the 2024 United Kingdom general election, the constituency changes described as following:

The electorate will be reduced to bring it within the permitted range by transferring northern parts, including the town of East Grinstead to the newly created constituency of East Grinstead and Uckfield. This will be partly offset by adding the Hassocks, and Hurstpierpoint and Downs wards from Arundel and South Downs.

History

The constituency was created in 1974 from parts of the seats of Lewes and East Grinstead, and has undergone significant boundary changes at every periodical review that it has been around for. Prior to 1973, the local government district had actually been a part of East Sussex, but as a result of delayed implementation of the Local Government Act 1972, it was almost wholly moved into West Sussex.

At the 1983 general election, it gained some of the wards (including East Grinstead itself) previously contained in the East Grinstead constituency (which disappeared at that election, its last MP Geoffrey Johnson Smith contested and won the new seat of Wealden in East Sussex), and at the 1997 election, it gained many of the semi-rural wards with smaller communities between East Grinstead and Crawley.

From its creation in 1983 to the present, it has been a Conservative seat, with the primary opposition until the 2015 election being the Liberal Democrats and their predecessors the Liberal Party. In 2015, there was a severe fall in Liberal Democrats support. Labour's candidate come second in the seat for the first time in its history. In 2017, Labour consolidated this lead at the 2017 General Election by gaining almost double the votes of the Liberal Democrats.

In the 2016 European Union referendum, Mid Sussex voted for the United Kingdom to remain a member of the European Union. Despite this, Soames called for MPs to back Theresa May's withdrawal agreement. However, he was one of the 21 Conservative rebels who voted to allow Parliament to vote to legislate to prevent a no deal Brexit on 3 September 2019, and subsequently became an independent, after the rebels had the Conservative whip removed. He then decided not to stand for re-election although he had the whip restored before dissolution.^[6]

The Liberal Democrats regained a clear second place in the 2019 General Election, and won the seat in 2024 following boundary changes.
