Justin Trudeau has won the leadership of the Liberal Party of Canada in commanding fashion.
The charismatic, 41-year-old son of former prime minister Pierre Trudeau won on the first ballot, easily topping his nearest rivals Joyce Murray and Martha Hall Findlay.
Trudeau took 80 per cent of the vote. Murray finished a distant second with just more than 10 per cent of the vote. Hall Findlay finished with 5.7 per cent, Martin Cauchon finished with 2.6 per cent, and Deborah Coyne and Karen McCrimmon both finished with 0.7 per cent.
Trudeau got 24,668 points, well surpassing the 15,401 needed to secure the victory. His total compared with 3,130 for Murray, his closest competitor. Hall Findlay garnered 1,760 while Cauchon (815), Coyne (214) and McCrimmon (210) were far behind.
Conservatives immediately issued a press release congratulating Trudeau on his win and slamming his lack of political experience.
"Justin Trudeau may have a famous last name, but in a time of global economic uncertainty, he doesn’t have the judgment or experience to be prime minister," Conservative spokesman Fred DeLorey said.
About 1,000 Liberals gathered at a special event in Ottawa to learn the results. The turnout for the vote was 82 per cent after 104,552 people cast a ballot by the time polls closed at 3 p.m. on Sunday out of a total of 127,264 registered voters.
Trudeau, a father of two young children with wife Sophie Grégoire, was first elected in the Montreal riding of Papineau in 2008.
