Membership of the Labour Party dipped below 400,000 for the first time since 2015, according to recently published documents.

According to the party’s annual accounts, Labour lost 37,000 members during 2023, with a total membership of 370,450 at the end of last year.

The figure is significantly down from its peak of 564,443 in 2017.
