Canadian Prime Minister Justin Trudeau announced his resignation on Monday following a decline in popularity and a crisis within his government that has left him politically weakened. Trudeau is stepping down as leader of the Liberal Party but will remain as prime minister until a new leader is appointed. Having led the Canadian government for nearly a decade, his resignation marks the end of an era. The Conservative Party, led by Pierre Poilievre, now leads the polls by a wide margin, while the Liberals are in free fall, having lost much of their electorate’s support. Elections must be held by October at the latest.
