It was initially believed that Paul Martin's Liberals would win a majority of seats in Quebec at the expense of the Bloc, but the Liberal Party's fortunes were instead damaged by the sponsorship scandal, in which some advertising revenues approved by the Chrétien government to promote Canadian federalism in Quebec were found to have been misused. The Bloc soon re-established itself as the dominant federal party in Quebec, and the Liberals were reduced to a minority government in the 2004 federal election. Plamondon was chosen as BQ caucus chair in the new parliament.
