Justin Trudeau has announced he will step down after nine years as Canadian prime minister in the face of a mounting set of crises, but stay in office until a replacement party leader is chosen.

Trudeau, who is facing pressure from members of his own Liberal party to quit ahead of federal elections in Canada later this year, has been a target of frequent attacks from U.S. President-elect Donald Trump.

Canadian Prime Minister Justin Trudeau is likely to announce his resignation as leader of the Liberal Party this week, the Globe and Mail reported, citing information from three people it didn’t name.
