Erith & Thamesmead.

Erith and Thamesmead sits on the south bank of the Thames in east London, a wholly urban seat of roughly 131,000 residents with a median age of 35, where fewer than half are recorded as White. It is built around two centres: the Greenwich-side neighbourhoods, nearly two-thirds of the seat, and the Bexley side at just over a third. The seat straddles a council boundary -- five wards fall under Greenwich and three under Bexley, both London borough authorities -- so local services answer to two separate town halls.

That split shapes the local politics. Across the twenty most recent ward contests, in May 2026, Labour and its Co-operative variant took all but one, with Reform UK claiming a single ward in Belvedere on the Bexley side -- a pattern pointing to durable Labour dominance, even as turnouts in the Thamesmead wards ran low. The parliamentary picture is firmer still: Labour won in 2024 on 55.1 per cent, with Reform UK a distant runner-up on 14.7 per cent, where in 2019 the challenger had been the Conservatives. Abena Oppong-Asare, Labour's MP here since 2019, sits within that majority.

On the figures available, the seat reads as safely held, with no obvious challenger consolidating behind Labour. Recent local coverage has carried a largely administrative tenor, centred on council business and the slower questions of estate regeneration. The constituency does register elevated crime, with vehicle crime running roughly three times the constituency average and anti-social behaviour and drug offences also markedly above it. The direction of travel looks settled rather than contested.
