Justin Trudeau is expected to announce as early as Monday that he will resign as Liberal Party Leader, three sources said Sunday, as the Prime Minister faces a caucus revolt and dismal public opinion polls that show his party will likely be swept out of power by Pierre Poilievre’s Conservatives in a landslide victory.

The sources stressed that they don’t know definitely when Mr. Trudeau will announce his plans to leave but said they expect it will happen before a key national caucus meeting on Wednesday. The Globe and Mail is not identifying the sources because they were not authorized to discuss internal party matters.
