The polling firm’s latest round of Westminster voting intention figures for London show Labour has significantly increased its lead since the last poll at last year’s mayoral elections.
Labour are currently on 55% of the vote (+4 since May 2021) while the Conservatives are on 23% (-10) - 32 points behind.
It is the opposition’s biggest lead in London since at least 2010, when London polling began.
Labour have held on to 73% of those who voted for them at the last general election, while the Tories are holding on to 50% of their 2019 electorate – the same figure as nationally.
YouGov also collected voting intention figures from the capital prior to the outbreak of the party scandal last week.
It suggests that the fall in Conservative support came before these more recent revelations, with the Conservatives holding steady on 23% of the vote compared to January 7-10.
While Labour have increased their vote share by four points, from 51% last week.
The Liberal Democrats currently have 9% of the vote (+2), while the Greens have 7% (no change) and Reform UK have 3% (+2).
