The Bloc Québécois was formed in 1990 as an informal coalition of Progressive Conservative and Liberal Members of Parliament from Quebec, who left their original parties around the time of the defeat of the Meech Lake Accord. The party was intended to be temporary and was given the goal of the promotion of sovereignty at the federal level. The party aimed to disband following a successful referendum on secession from Canada. As with most parties, it has gained and lost prominent supporters over the years.[26]
