Conservative leader Andrew Scheer said he was “sickened and appalled by the testimony of former justice minister about the SNC-Lavalin case”.

Asked about the incendiary calls from the opposition that he quit, Mr Trudeau said Candanians will have a clear choice in October's federal election.

Justin Trudeau on BRINK: Rival vows to ‘RAMP UP PRESSURE’ to OUST PM

Mr Trudeau is being pressured to reveal what he knows about whether officials from his office inappropriately pressured a former cabinet minister to become involved with a prosecution on construction giant SNC-Lavalin.

Former justice minister Jody Wilson-Raybould on Wednesday said she was pressured into being lenient to SNC-Lavalin who were facing a bribery trial.

Her comments to the House of Commons justice Committee have stirred what is the biggest crisis in the presidency of Mr Trudeau.

Ms Wilson-Raybould said she and her staff were faced with four months of “sustained” and “inappropriate effort” to advocate for a potential deferred prosecution agreement for SNS-Lavalin.

Mr Trudeau told a televised news conference in Montreal: "I strongly maintain, as I have from the beginning, that I and my staff always acted appropriately and professionally.

"I therefore completely disagree with (Wilson-Raybould's) characterization of events."
