Keir Starmer will be Britain’s next prime minister with his Labour Party set to win a massive majority in a parliamentary election, with Prime Minister Rishi Sunak conceding defeat after an historic thumping for his Conservative Party.

Centre-left Labour was on course to capture 410 of the 650 seats in parliament, according to an exit poll, an astonishing reversal of fortunes from five years ago when it suffered its worst performance since 1935.

The result would give Labour a majority of 170 and would bring the curtain down on 14 years of increasingly tumultuous Conservative-led government.

As of 0400 GMT, many of the biggest names in Conservative politics had lost their seat, including the pro-Brexit Jacob Rees-Mogg and former leadership contender Penny Mordaunt. Sunak and his finance minister Jeremy Hunt retained their seats, the latter unexpectedly.

Sunak’s party were forecast to only win 131 seats, the worst electoral performance in its history, as voters punished them for a cost-of-living crisis, and years of instability and in-fighting which has seen five different prime ministers since the Brexit vote of 2016.
