Treasury Board president Jane Philpott has quit her position as the Trudeau government's crisis over the SNC Lavalin affair deepens.
Jane Philpott, one of Justin Trudeau's most trusted ministers, has resigned from cabinet as the Liberal government struggles with a scandal over the SNC-Lavalin affair.
"I must abide by my core values, my ethical responsibilities and constitutional obligations," she said in a statement. "There can be a cost to acting on one's principles, but there is a bigger cost to abandoning them."
In that letter sent to the Prime Minister, Philpott says the evidence of efforts by politicians and/or officials to pressure the former attorney general on the SNC Lavalin file have serious concerns for her.
Philpott had most recently been president of the treasury board. She notes given current circumstances, "it is untenable for me to serve in Cabinet."
She said the constitutional convention of cabinet solidarity means ministers are expected to defend all cabinet decisions and other ministers publicly, and must speak in support of the government and its policies.
Philpott is a close ally of Jody Wilson-Raybould, the former justice minister and attorney general at the centre of the SNC-Lavalin scandal. Wilson-Raybould testified before a Commons committee last week that 11 officials in the Prime Minister's Office and other offices inappropriately pressured her to override a decision to prosecute SNC-Lavalin on bribery charges.
