Former governor general Ed Schreyer says the Liberal-NDP coalition should get a chance to govern if the Conservatives are defeated in the House of Commons on Monday.

He's telling the CBC that the Canadian system requires that a government have the confidence of Parliament.

Were he still in office, he says, he would have no choice but to ask the coalition to step in if Stephen Harper and his Tories are defeated.

He also says he would be leery of a request to suspend Parliament until the end of January, which would defer a confidence vote and a potential defeat.

Proroguing the Commons for a few days or a week might be fine, but Parliament must not be thwarted, he says.
