Mulroney, (Martin) Brian (1939– ) Canadian statesman, prime minister (1984–93). In 1983, Mulroney became an MP and leader of the
Progressive Conservative Party. In his first term, he signed the Meech Lake Accord (1985), which constitutionally made
Québec a ‘distinct society’. In 1987 he negotiated a free trade treaty with the US, which led to the 1992
North American Free Trade Agreement (NAFTA). The status of Québec continued to vex his administration and, following defeat in a national referendum, Mulroney resigned. Kim Campbell succeeded him as prime minister and party leader.
