WATCH: PM blames SNC-Lavalin controversy on "erosion of trust"

Prime Minister Justin Trudeau says there was an "erosion of trust" between his office and former justice minister Jody Wilson-Raybould over the SNC-Lavalin case.

In comments heard live on NEWSTALK 1010 the Prime Minister admitted he could have acted differently.

Trudeau announced the government will ask for advice on the dual role of the Attorney General and Justice Minister and also look at policies and practices involving cabinet, political staff, and bureaucrats.

Trudeau promised to do better in future. But while he'll adopt a more conciliatory tone, well-placed sources say Trudeau will continue to insist there was no unethical or illegal behaviour involved.

Trudeau's government has been reeling for the past month since allegations first surfaced that Wilson-Raybould was improperly pressured to stop a criminal prosecution of SNC-Lavalin and was punished for her refusal to give in by being moved to veterans affairs in an early January cabinet shuffle. She resigned from cabinet shortly after the controversy erupted.
