Under the name 'preferential' or 'elimination ballot' or "alternative vote", IRV was used in the British Columbia's general elections of 1952 and 1953. IRV was initially brought in by the governing coalition consisting of the Liberal and Conservative parties. In the next election many CCF supporters chose the relatively unknown Social Credit Party, a minor party that had never held any seats in the British Columbia legislature, as their second choice. The Social Credit Party achieved an upset victory in the 1952 election, winning 19 seats in the 48-member legislature to 18 for the CCF, 6 for the Liberals and 4 for the Conservatives. The Socreds formed a short-lived minority government until the 1953 election, in which they won a majority of seats (28 of 48). After the 1953 election, the Liberal and renamed Progressive Conservative Parties were reduced to third parties in the province, and first-past-the-post was reinstated by the government.
