The allegation came as at least 56 MPs, including three ministers, are probed over allegations of sexual misconduct by parliament’s own complaints office.

The Conservative party has been accused of misogyny after the Mail on Sunday last week quoted unnamed Tory MPs accusing the deputy leader of the opposition Labour party, Angela Rayner, of trying to distract Prime Minister Boris Johnson with her legs.

British media reported that the porn claim was first made during a meeting of up to 50 Conservative lawmakers on Tuesday night.
