Lewisham West & East Dulwich.

Lewisham West and East Dulwich is a wholly urban seat in south-east London, its 106,000 residents drawn from a built-up sprawl that straddles two boroughs. Around two-thirds sits within Lewisham; the remainder, taking in the Dulwich fringe, falls inside Southwark. This is a young, educated and mixed area: the median age is 36, well over half of residents hold a degree, and a little under two-fifths are from a minority ethnic background. Local services run through two London borough authorities -- Lewisham across four of the seat's wards, Southwark across the other three -- so it answers to a divided municipal map rather than a single town hall.

That map has lately tilted in one direction. Across the most recent ward contests, held in May 2026, the Green Party took fifteen of nineteen seats, with Labour and its Co-operative ally holding the rest, a pattern that suggests Green strength is now embedded at the local tier. The parliamentary picture remains a different contest. At the 2024 general election -- the first fought on these 2023 boundaries -- Labour's Ellie Reeves, the sitting MP since 2017, won 59 per cent of the vote, with the Greens a distant second on 19.

For now the seat looks secure for Labour even as the Greens advance beneath it, and recent local coverage has leaned towards planning disputes and stalled development rather than national drama. Vehicle crime appears to run well above the comparable average, with anti-social behaviour also somewhat elevated. The direction of travel is one of a safe Labour seat with a restless local base.
