The Commons Speaker, John Bercow, has said MPs have the right to attempt to block Brexit using the parliamentary process, rather than feeling obliged to vote in line with the referendum result.
In a wide-ranging Q&A, Bercow also referred to the Daily Mail as the Daily Fail for its criticism of parliaments new £7m education centre, though he himself has often been the target of the newspapers attacks.
Bercow was the target of a short-lived plot by Conservative MPs to oust him from the role, which he has held since 2009, with several alleging he had failed to be impartial having declared he voted remain in the EU referendum, among other accusations.
Speaking to the Hansard Society, Bercow said it was an opinion, rather than a constitutional fact that MPs were obliged to vote through Brexit because of the referendum result.
There will be some members of parliament who say: I want to be able at the end of all this if Im not satisfied, to say no, to try to persuade other members of parliament to say no, and to hope that no might delay Brexit or prevent Brexit, he said, in comments reported by Politico. Do they have a right to argue that point of view? They absolutely do.
