Labour’s Jim Dickson has stepped down as member for Herne Hill and Loughborough Junction ward in Lambeth.
The 61-year-old has been MP for Dartford since July, when he overturned a 19,000 majority to win the seat of the Tories.
A by-election will be held to select Dickson’s successor in Herne Hill and Loughborough Junction on May 1.
Dickson was first elected to Lambeth Council in 1990.
He served as leader of the council between 1994 and 2000 and was cabinet member for health before his election to Parliament last year.
At the 2022 local elections, Dickson received the most votes of all candidates in Herne Hill and Loughborough Junction. He finished first with 2,429 votes (18 per cent) and was elected alongside fellow Labour candidates, Pauline George and Deepak Sardiwal.
Green candidate Celeste Hicks was the nearest contender for a seat, finishing fourth with 1,838 votes (13 per cent).
Councillor Claire Holland, leader of Lambeth Council, thanked Dickson for his ‘unrivalled service to the borough’ over his 35 years as a councillor.
She said: “He has worked incredibly hard for the people living in his ward, and also for the whole borough. In particular in recent years as our health lead, supporting communities through the Covid-19 pandemic and leading Lambeth Council’s crucial work to tackle health inequalities.”
Jim Dickson has been contacted for comment.
