The New Democratic Party is a major social democratic federal political party in Canada. The current leader of the NDP is Thomas Mulcair, who was elected in the 2012 leadership election. The NDP was founded in 1961 out of the merger of the Co-operative Commonwealth Federation with the Canadian Labour Congress. The provincial wing of the NDP in Manitoba currently forms the government in that province. Provincial parties have previously formed governments in British Columbia, Nova Scotia, Ontario, and Saskatchewan, and the territorial party formed the government in Yukon from 1985–1992 and 1996–2000. In the 2011 federal election under the leadership of Jack Layton, the NDP won the second-most seats in the Canadian House of Commons, gaining the title of Official Opposition for the first time in Canadian history.
