New Democrats pulled their support for the minority Liberal government on Friday, throwing the beleaguered Prime Minister’s tenure into further doubt just minutes before Justin Trudeau planned to shuffle his cabinet.

“The NDP will vote to bring this government down, and give Canadians a chance to vote for a government who will work for them. No matter who is leading the Liberal Party, this government’s time is up,” said NDP Leader Jagmeet Singh in a letter posted on social media.

“We will put forward a clear motion of non-confidence in the next sitting of the House of Commons.”

The NDP were the last party in the House of Commons to give their support to the minority Liberals in the wake of Chrystia Freeland’s surprise resignation as finance minister and deputy prime minister on Monday.
