The Brexit party’s support increased by two points to 26% of the vote in the latest Opinium poll – for the Observer – which asked people how they would vote in the next Westminster election.

Labour is in second place on 22%, but its support has fallen by seven points over the past two weeks. The Tories are third on 17%, with their support down five points, and the Lib Dems are up five points, on 16% of the vote.
