London mayor election LIVE: Polls open as Sadiq Khan and Susan Hall battle for City Hall [Video]

Thirteen candidates are battling it out on election day, which kicked off as voting stations opened at 7am, with millions also set to vote to elect a new London Assembly.

The Savanta survey for the Centre for London put the Labour mayor on 42 per cent and Tory candidate 32 per cent.

Voters are heading to the polls across the country in a series of local elections seen as the final test of public opinion before Rishi Sunak goes to the country later this year.

Forecasts suggest the Tories could lose up to half of the council seats they are defending, with Chancellor Jeremy Hunt saying the party expects to suffer “significant losses”.
