Former central banker Mark Carney is due to formally kick off his bid to replace Justin Trudeau as the head of Canada’s Liberal Party and the country’s prime minister on Thursday, with the leader of the opposition already attacking his record.

Mark Carney will launch his candidacy for the Liberal Party leadership at an event in Edmonton on Thursday, according to a notice from Calgary Skyview MP George Chahal.

Liberal MPs are starting to reveal which candidates they're backing in the race to replace Justin Trudeau, just as the presumed front-runners get ready to declare they're running.
