Nigel Farage’s Reform UK has secured victory in Runcorn and Helsby by just six votes, overturning a large Labour majority in a blow to Sir Keir Starmer in his first by-election test as prime minister.
The party set a new record for the smallest majority at a parliamentary by-election since the end of the Second World War.
MP Sarah Pochin’s narrow victory saw Reform take a constituency which Labour won with a majority of almost 14,700 less than 12 months ago.
The result came as Reform made large gains against both Labour and the Conservatives across England in local elections, with Farage claiming Reform is "now the main opposition party" and that a “big moment” was taking place in UK politics.
