A liberal MP wrote to the federal caucus expressing his opinion that Prime Minister Justin Trudeau should resign.

Wayne Long, the MP for New Brunswick, stated in a brief note obtained by CTV News: "For the future of our party and for the good of our country, we need new leadership and a new direction."

He said, "The voters have spoken loudly and clearly; they want change. I agree with that."

Long has already indicated that he does not plan to run again. He joins former Trudeau liberal cabinet minister Catherine McKenna and a small but growing list of other party believers who have officially come out in the days following the shocking Toronto Saint Paul incident, as the defeat in the by-election is a call for the Prime Minister to step down.

McKenna said in a statement to CTV News: “The Liberal Party is not about one person. It's about the values it represents and about improving the lives of Canadians.” "The Prime Minister has a legacy to be proud of, but it's time for new ideas, new energy, and new leadership. There is too much at stake in this election, especially regarding the economy and climate."

Recently, McKenna was quoted saying that former Bank of Canada Governor and leadership competitor, who has been the subject of much speculation, Mark Carney would be a good candidate.

Long said he wrote to his fellow MPs so they would know his position "clearly and directly."

Other MPs quietly expressed deep concerns over the future of the party's political and electoral fortunes - either without making some significant structural changes to its frontbench and inner circle or under Trudeau's leadership at all - while government ministers lined up behind him when questioned.

Earlier this week, without directly addressing leadership questions, Trudeau said he heard people's concerns and acknowledged that he and his team "have a lot of work to do to achieve tangible and real progress that Canadians across the country can see and feel."

Reports indicated that the Prime Minister's office reached out to parliamentarians this week, in the absence of a party-wide caucus meeting.
