Clapham & Brixton Hill.

Clapham and Brixton Hill is a dense inner-London seat carved from the London Borough of Lambeth, which alone runs local services across the four wards within its boundary. The built-up area of Lambeth covers effectively the whole constituency, so this is urban terrain rather than a network of distinct towns. Its character is young and highly educated: the median age is 31 and close to three in five residents hold a degree. Just over half of its roughly 115,000 residents are recorded as White.

The local political picture has been moving. Across the most recent ward contests in May 2026, the Green Party took the largest share of seats, ahead of Labour, with the Liberal Democrats and Labour Co-operative also returning members. Turnouts varied sharply, from roughly 4,400 in Clapham East to over 13,000 in Brixton Acre Lane. At Westminster the seat looks comfortably Labour: in 2024, the first General Election on these 2023 boundaries, Labour won 56.5% to the Liberal Democrats' 14.4%. The sitting member, Bell Ribeiro-Addy, has held it since 2019 and broke with her party on four whipped divisions in the past 90 days.

The tension worth watching is between that secure Westminster margin and a council picture in visible flux, with control having shifted at borough level and recent coverage dominated by the reshaping of local power. Crime data adds a note, with theft from the person and other property thefts appearing to run well above comparable seats. On the figures available the seat looks safe for now, even as the ground beneath the council moves.
