John Bercow enraged MPs and faced calls to resign after he was found to have affixed a sticker to his car window which said: “b----cks to Brexit, it’s not a done deal”.

In March, the Speaker of the House of Commons was accused by furious MPs of “blatant arrogance” over the decision to place the sticker in his black 4x4, which was seen in his private parking space.

It is understood that the Speaker’s wife drives a different car, while Mr Bercow’s car has a personalised number plate.

His office declined to comment on the issue.

It came after Mr Bercow was embroiled in a row over allegations that he bullied his former secretary Kate Emms, who was signed off work sick in 2011.
