Canadian Prime Minister Justin Trudeau was hit hard when a second member of his cabinet resigned on Monday, saying he had lost faith in the government’s handling of a political scandal in which he is embroiled.

The departure of new Treasury Board President Jane Philpott, who was in charge of government overhead, robs Trudeau of another powerful minister months before an election that polls suggest he could lose.

“I have unfortunately lost faith in the way the government has handled this issue and how it has reacted to the issues raised,” she said in a statement.

Trudeau told a Liberal Party rally in Toronto that he was disappointed but understood why she quit.

Last week, the opposition called for Trudeau’s resignation and the launch of a federal inquiry into Jody’s allegations during her testimony in February before the House of Commons Judiciary Committee.

Jody claimed that Trudeau, one of her ministers and close advisers exerted “inappropriate” pressure on her, including “veiled threats”, to intervene in a criminal case, and that they harassed to get the matter settled out of court. The former minister refused and the trial is about to begin.

SNC-Lavalin was charged in 2015 with corruption, suspected of having bribed officials in Libya between 2001 and 2011 to obtain government contracts under the regime of former leader Muammar Gaddafi.

Jane is a close friend of Jody, who resigned Feb. 12 after being reassigned to a minor ministry in January. Jody said last week she was convinced her refusal to help SNC-Lavalin was the reason for her departure from the Justice Department.
