At the start of the 2019 campaign, the Conservatives led Labour across AB, C1 and C2 voters, while Labour maintained a 2.5 point lead among DE voters.
By the end of the campaign, 9% of these working class voters had swung to the Conservatives, largely from the Brexit Party. The 22% of AB voters who had begun the campaign intending to vote Liberal Democrat split between other parties, with 2% going to the Conservatives and 4% to Labour.
