London is one of the few areas of the country where Labour is already in a very strong position, holding more than two-thirds of seats in the capital, and the election could see the party advance even further to make a string of gains.
A redrawing of boundaries means London now has 75 constituencies, up from 73 in 2019, and had the last election been fought on these new boundaries it is calculated the Labour would have won 52 seats, the Conservatives 20 and the Liberal Democrats three.
