As rumours swirl around Parliament Hill about efforts within the Liberal caucus to urge Justin Trudeau to resign as party leader, Liberal MPs are saying publicly that it's still an internal matter for the party.

Mr Trudeau and his party have traversed an arc from heroic to hapless during nine years in office, and today are despised by many in Canada. Less than a quarter of the electorate plans to vote for him.

A growing number of Liberal MPs have been meeting and coordinating to find a way forward for their party following a couple of surprising losses in the byelection in June

Last week saw four more cabinet ministers tell Prime Minister Justin Trudeau they won’t run for re-election, adding to a growing cabinet exodus and other MP resignations this year.
