UPDATE 3-Canada opposition leader demands PM Trudeau quit over ethics allegations

The leader of Canada's main opposition party demanded on Wednesday that Prime Minister Justin Trudeau quit after a former justice minister said government officials inappropriately pressured her to help a major firm avoid a bribery trial. The allegations by Jody Wilson-Raybould dramatically deepened the biggest crisis of Trudeau's tenure just months ahead of an October election in which his Liberals face a tough fight.

Wilson-Raybould told the House of Commons justice committee that she had confronted Trudeau over what she called inappropriate pressure to help construction firm SNC-Lavalin Group Inc evade a corruption trial. Andrew Scheer, leader of the official opposition Conservative Party, demanded the resignation of what he called a disgraced prime minister.

"He can no longer, with a clear conscience, continue to lead this nation," Scheer told reporters, calling for police to immediately probe the matter. Trudeau is due to address reporters later on Wednesday.
