Not only did Spencer win, but she won well, significantly outperforming the expectations of the polls. Rather than winning narrowly, the party won 40.7%, enough to put them as much as 12 points ahead of second placed Reform. It represented as much as a 27.5 point increase on the party's share in 2024. Labour, who had not hitherto lost an election in the area since 1931, fell into third place. The party's 25.4% of the vote represented a near halving of their 50.8% of the vote in 2024 and the 13th biggest ever fall in the party's support in a by-election. Meanwhile, the Conservatives lost their deposit with just 1.9% of the vote, their worst ever by-election result.
