Ellesmere Port and Neston was a constituency[n 1] represented in the House of Commons of the UK Parliament since 2015 by Justin Madders of the Labour Party.

As a consequence of these changes, the constituency will be renamed Ellesmere Port and Bromborough, to be first contested at the 2024 general election.

[4] 1983–1997: The Borough of Ellesmere Port and Neston, and the City of Chester wards of Elton, Mollington, and Saughall.

However, before the new boundaries came into force for the 2010 election, the districts making up the county of Cheshire were abolished on 1 April 2009, being replaced by four unitary authorities.

Consequently, the constituency's boundaries became: The Cheshire West and Chester wards of Chester Villages (part), Ellesmere Port Town, Elton, Grange, Ledsham and Manor, Little Neston and Burton (part), Neston, Netherpool, Parkgate, Rossmore, St Paul's, Strawberry, Sutton, Whitby, and Willaston and Thornton.
