• Trudeau expected to announcement resign before caucus meeting on Wednesday - newspaper report


• Ruling Liberals trailing badly in polls, election must be held by late October

Canadian Prime Minister Justin Trudeau is increasingly likely to announce he intends to step down, though he has not made a final decision, a source familiar with Trudeau's thinking said on Sunday.

The source spoke to Reuters after the Globe and Mail reported that Trudeau was expected to announce as early as Monday that he would resign as leader of Canada's ruling Liberal Party after nine years in office.

The source requested anonymity because they were not authorised to speak publicly.
