Liverpool, West Derby is a constituency[n 1] represented in the House of Commons of the UK Parliament since 2019 by Ian Byrne of the Labour Party.

2010–2024: The City of Liverpool wards of Croxteth, Knotty Ash, Norris Green, Tuebrook and Stoneycroft, West Derby, and Yew Tree.

Following their review of parliamentary representation in Merseyside, the Boundary Commission created a modified West Derby constituency, which was fought at the 2010 general election.

The commission's initial proposal to create a cross-border "Croxteth and Kirkby" constituency (which would have contained electoral wards from Knowsley borough, as well as from Liverpool) was dropped on its public consultation.

Sir Frederick Edwin Smith, then Solicitor-General in the David Lloyd George Coalition Government, was returned for Liverpool West Derby at the 1918 general election; when constituency reorganisation abolished his former neighbouring Walton seat.

[9] Stephen Twigg ousted Michael Portillo in the normally right-leaning Enfield Southgate seat and represented it from 1997 until the 2005 general election; briefly serving as schools minister before that year's general election, which he lost, before five years later, standing for this normally left-leaning seat in Liverpool.
