PM expected to launch election campaign Sunday

Liberal Leader Stéphane Dion adjourned his party's caucus retreat early on Thursday, amid reports that Prime Minister Stephen Harper will pull the plug on his minority Conservative government on Sunday.

Harper is expected to visit Gov. Gen. Michaëlle Jean at 9 a.m. ET on Sunday and ask her to dissolve Parliament, the Canadian Press reported Thursday.

Canadians would then go to the polls on Oct. 14.

Liberal MPs have been sent back to their ridings to prepare for the long anticipated election call.

The Liberal caucus was in Winnipeg and was to have wrapped up on Thursday. But Dion cancelled his closing speech.

The prime minister was with his cabinet Thursday for a pre-election meeting in Meech Lake, Que.
