“Change begins now. And it feels good. I have to be honest.

“Four and a half years of work changing the party. This is what it is for: a changed Labour party, ready to serve our country, ready to restore Britain to the service of working people.”

Starmer said great responsibility comes with Labour’s mandate, adding: “We must return politics to public service so that politics can be a force for truth.”

Starmer said the “values of this changed Labour party” are the “driving principle for a new government: country first, party second.”

Starmer will replace Rishi Sunak as the new prime minister, according to the results.

In a solemn address, he expressed his regret to the nation and acknowledged the voters' clear call for change.

"I have given this job my all but you have sent a clear signal that the government of the United Kingdom must change and yours is the only judgment that matters. I have heard your anger, your disappointment. And I take responsibility for this loss."

Starmer will then go to Buckingham Palace to accept the duty to form a new government from the monarch, before a speech in Number 10.
