Sarah Joanne Pochin (née Hyde, born June 1969) is a British politician who has been the Member of Parliament (MP) for Runcorn and Helsby since a by-election in May 2025. She is Reform UK’s first female MP. She was previously the Mayor of Cheshire East and a local councillor, as well as a justice of the peace (JP). Formerly a Conservative councillor who later sat as an independent member, she left the party and joined Reform UK. She currently holds the record for the smallest margin of victory in modern British by-election history, having overturned Labour's 14,700 majority from the 2024 general election by just six votes.
