The seat merged about half of the previous constituency of Billericay with smaller parts of the former Basildon constituency – mostly around the centre of Basildon.
The MP until the dissolution of parliament in May 2024 was the Conservative John Baron, who had held the seat since its creation, but announced in October 2023 that he would be stepping down.[5] His party's choice of the national chairman as its candidate to succeed him was controversially made just 48 hours before the deadline from a shortlist of one, to the anger of the local association.[6]
