Trudeau will remain in office until the party elects a new leader.

Canadian Prime Minister Justin Trudeau resigned on Monday as leader of the Liberal Party, a position he has held for eleven years, in the face of a growing lack of confidence in the ranks of the party and the expected defeat in the elections scheduled for October, according to polls.

"I intend to step down as party leader, as prime minister, after the party elects its next leader," Trudeau said. "This country deserves a real choice in the next election," he said.

"It's become clear to me that if I have to fight internal battles, I cannot be the best choice in this election," Trudeau said.

Trudeau announced his decision just days before the Liberal Party's national executive is due to meet this week to discuss the next steps at a time when most polls have him widely defeated by the conservative opposition in the upcoming elections.

Winner of three consecutive elections - in 2015, 2019 and 2021 - he has been losing momentum in recent years after several political setbacks, the resignation of key allies - such as his finance minister - and disastrous opinion polls.

Added to this is a Donald Trump - of whom he was once the antithesis in North America - who has been kicking a dead horse after winning the election, referring to himself as the governor of the "51st state" and threatening to impose heavy tariffs.
