OTTAWA, Sept 10 (Reuters) – Canada’s Conservatives on Saturday chose Pierre Poilievre, a veteran MP who has promoted bitcoin as a way to fight inflation, to lead the party’s bid to oust the Liberals and Prime Minister Justin Trudeau. Poilievre, 43, won the leadership in the first round of a ranked vote in which more than 400,000 members voted. Poilievre becomes the sixth Conservative leader since 2015, a period in which they have lost three elections to Trudeau. Poilievre defeated his main rival Jean Charest, a former Quebec premier, and three others in a campaign that slammed Trudeau and the central bank governor for failing to rein in runaway inflation.
