The House of Commons voted for a general election on Thursday 12 December by 438 to 20.
Earlier opposition parties had tried to change the date of the election to 9 December, but this was voted down by 315 to 295.
And many Labour MPs are deeply unhappy at the prospect of an election in the run-up to Christmas.
More than 50 signed an amendment calling for the election to be delayed to May 2020.
104 of the party’s MPs decided not to vote on the poll, with 11 voting to block it.
Joining the Labour dissenters, independent MPs and Welsh nationalists took the numbers voting to block the snap poll to 20.
