Runcorn & Helsby.

Runcorn and Helsby sits in the North West of England, a seat built on 2023 boundaries around a single dominant town and a scattering of smaller places beyond it. Runcorn itself holds close to two-thirds of the population, with the market towns of Frodsham and Helsby and a band of rural and dispersed settlement making up most of the rest. The seat crosses two unitary authorities: Halton, which runs services across nine of its wards, and Cheshire West and Chester, which covers four to the south and east. The population of around 91,000 is older than the national norm at a median of 43, overwhelmingly White, and modestly educated by graduate measures.

The local political picture has moved sharply. Across the most recent round of Halton ward contests, held in May 2026, Reform UK took the clear majority of seats, winning nine of the sixteen wards counted across both councils. The Cheshire West and Chester wards were last fought in 2023 and split between Labour, the Conservatives and a Green gain in Helsby, leaving that side of the seat on an older verdict. At the 2024 General Election -- the first on these boundaries -- Labour won comfortably on 52.9%, with Reform a distant runner-up on 18.1%. The sitting MP, Sarah Pochin of Reform UK, took the seat at a by-election the following year, a result that inverted that margin.

The seat now reads as one in flux rather than settled. A Labour win in 2024 has given way within two years to a Reform-held seat and a Reform-leaning ward map across the Halton side, while the Cheshire West wards await a fresh test. Recent coverage has carried a contested, unresolved edge, with attention still drawn to the disputed circumstances of the by-election alongside more routine council business. Drugs offences appear to run around a third above the comparable constituency average. On the figures available the direction of travel favours Reform, but a seat that swung this far this fast cannot yet be read as fixed.
