Sir Keir Starmer has won the race to replace Jeremy Corbyn as leader of the Labour Party.
He said it was the "honour and priviledge of my life" and vowed to lead the party into "a new era, with confidence and hope".
Sir Keir, who remained frontrunner throughout the contest, won the election with 56.2 per cent of the vote, while Rebecca Long-Bailey took 27.6 per cent and Lisa Nandy 16.2 per cent.
His victory speech was recorded and shared online after the special party conference was cancelled due to coronavirus.
Addressing the unprecedent challenge that Covid-19 is presenting to the country, the new opposition leader said he would "engage constructively" with the Prime Minister.
"Under my leadership we will engage constructively with the government, not opposition for opposition's sake.
"Not scoring party political points or making impossible demands. But with the courage to support where that's the right thing to do."
He also paid tribute to outgoing Mr Corbyn, saying he "led our party through some really difficult times" and "energised our movement".
Angela Rayner has been elected as his deputy, with 52.6 per cent of the vote.

"I know we face a long and difficult road ahead but it’s our responsibility to offer the better future that the citizens of our country deserve."
