Claude Wagner, a judge and a prominent Quebec Liberal cabinet minister who departed provincial politics in 1970, ran successfully as a Progressive Conservative in the 1972 federal election, and was the front-runner in the party leadership convention in 1976 before losing on the final ballot to Joe Clark. When Bourassa returned to politics in the 1980s, he worked closely with the federal Progressive Conservatives led by Brian Mulroney. During that decade, the Liberals won the majority of Quebec's seats in 1985 and 1989, while the PCs did so at the federal level in 1984 and 1988. Some Quebec Progressive Conservatives attempted to form a provincial party, the Progressive Conservative Party of Quebec, in the 1980s but this effort was not supported by the federal party and failed to win any seats.
