(CNN) Canada's prime minister has expelled two lawmakers from the ruling Liberal Party, saying "trust has been broken" after one accused the government of pressuring her to go easy on a major company accused of wrongdoing.

Jody Wilson-Raybould has said the government led by Prime Minister Justin Trudeau put pressure on her when she was Attorney-General, to help Montreal-based construction company SNC-Lavalin settle a criminal case and avoid prosecution.

She said in testimony to the House Justice Committee that she had faced "veiled threats" and "sustained" pressure to help SNC-Lavalin, a major employer in Canada, over allegations that it had bribed officials in Libya to secure contracts.

She resigned her government post soon after making the accusations.

The other lawmaker, Jane Philpott, who had held several portfolios in Trudeau's cabinet before becoming Treasury Board president, resigned last month , saying she had lost confidence in the government's handling of an inquiry into the allegations.
