OTTAWA — Liberal MPs are gearing up for a high stakes caucus meeting on Wednesday that could see multiple calls for Prime Minister Justin Trudeau to resign, but it is unclear what, if anything, will come of the internal revolt or if it will simply fizzle out.

Before the cabinet meeting, Liberal ministers on Tuesday were reaffirming their confidence in Trudeau in droves while downplaying the idea that dozens of MPs had added their signatures to a letter to ask the prime minister to step down for the good of the country.
