Which of the following is the ruling party?.

Canada’s minority Liberal government, under heavy pressure over a corruption scandal, looks set to lose a confidence vote next week, government and opposition officials said on Friday.
    Prime  Minister Paul Martin has proposed Parliament vote on his budget next Thursday and says he will call an election if he loses.
    "Of course we’ll lose the vote," a junior cabinet member told Reuters. If the IAberals fall next Thursday
it would open the way to a June 27 election.
    The Liberals and their left-leaning New Democrat allies have 151 seats in the 308-seat parliament, while the Conservatives and the separatist Bloc Quebecois have 153. The speaker of Parliament is a Liberal but he only votes in case of a tie. One seat is vacant.
