The surprise poll results are in contrast to polls leading up to the election that suggested Prime Minister David Cameron's party would not come close to a majority, and would be locked in a much tighter race with the opposition Labour Party, led by Ed Miliband -- predicted to gain 239 seats in the exit poll.
Cameron's Conservatives would need 326 for an outright majority in the 650-seat parliament.
If the exit poll is accurate, the Conservative Party would be in a commanding position to form the next government by seeking coalition partners from smaller parties.
