A Conservative MP has been accused of groping men in a bar in parliament before being escorted away by police.

Scotland Yard confirmed that officers had been called to the Strangers’ Bar after claims of “sexual touching” but added that no formal complaint had been made.

It is understood the serjeant at arms, who is in charge of security within the House of Commons, has also been informed.

The website Guido Fawkes reported that the MP – Ross Thomson – had given a statement to police before being escorted from the building.

Thomson, the MP for Aberdeen South and one of 12 Scottish Tories elected to the Commons in 2017, did not respond to a request for comment.

The incident follows a concerted bid by the authorities to clamp down on a late-night drinking culture in parliament.

Thomson, 31, joined dozens of MPs and researchers in the bar on Tuesday night after MPs had attended a number of events on the estate. The Strangers’ Bar is one of the most popular in Parliament – drinkers often move on to the terrace overlooking the Thames. The MP then walked outside the bar and was questioned by police before leaving the bar.

A Scotland Yard spokesperson said: “Police were called at approximately 23.00hrs on 5 February to a bar within the Palace of Westminster following a report of sexual touching.

“Officers attended and spoke to the parties involved – three men in their 20s and 30s. However, no formal allegations were made to the officers and no arrests were made.”

A spokesman for the Scottish Conservatives said: “We are aware of reports of an incident last night and the matter is being looked into. We have no further comment to make at this stage.”

In 2017 UK politics was hit by a series of revelations of inappropriate behaviour by MPs and those who work for them and with them. A report by Dame Laura Cox revealed that more than 200 parliamentary staffers claimed to have been groped and propositioned by male MPs.
