The Conservatives are investigating claims that a Tory MP was caught watching pornography on his mobile phone in the House of Commons chamber.
Chief whip Chris Heaton-Harris was looking into the “wholly unacceptable” allegations, with a spokeswoman vowing on Wednesday that “action will be taken”.
The investigation came after the Mirror and the Sun reported that the claims were aired during a meeting of Tory MPs in Westminster the night before.
According to the PA news agency, the investigation centred on allegations that a Conservative watched the adult video in the Commons chamber, but could not immediately establish whether the MP was a frontbencher.
A Conservative whips office spokeswoman said: “The chief whip is looking into this matter.
“This behaviour is wholly unacceptable and action will be taken.”
