A Scots MP says he was also a victim of the Tory accused of drunkenly groping other men in a Commons bar.

Aberdeen South MP Ross Thomson is already being investigated by party bosses after police were called to Westminster’s Strangers’ Bar earlier this month amid complaints about “sexual touching”.

The Daily Record can today reveal that a Scots MP alleges he also ­experienced unwanted physical contact from Thomson in a separate incident late last year.

He made an official statement to Parliament’s sexual harassment hotline last week and is in contact with Westminster’s ­Parliamentary Standards Commission.

Thomson, 31, has described the original claims against him as “completely false” but referred himself to the Tory Party’s in-house ­disciplinary panel.

The MP who made the fresh complaint said the development had convinced him to come forward about the earlier ­incident, which also occurred in Strangers’ Bar.

He also spoke of concerns that Thomson was trying to “gaslight” people – a term meaning ­the ­manipulation of a target to make them doubt their own memory.

The MP hit out at Thomson’s “brazen and persistent denials” about his conduct and “what has effectively been an attempt to gaslight those people he has assaulted”.

He added that, because people have felt “intimidated, humiliated and violated" by Thomson’s behaviour, “it has now pressed me to move beyond initial attempts to informally raise concerns and to now initiate a formal complaint”.

He added: “I hope this will give some reassurance to others who have been affected and have felt less able to come forward formally.”

There was speculation that a ­separate inquiry by Parliament’s ethics watchdog had been dropped because the original complaint came from someone other than the victim.

But the new revelation will likely ensure the allegations are probed by Standards Commissioner Kathryn Stone amid claims they are ­potentially proof of a “pattern of behaviour”.

The Record has spoken to multiple witnesses who were in the Commons bar on February 5 and saw the alleged incident with Thomson.

Catriona Matheson, the SNP’s head of communications in Westminster, expressed shock at ­Thomson’s denial, describing it as “jaw-dropping”.

She tweeted: “It was the talk of Parliament… because the bar was packed and there were multiple witnesses. I spoke to several people who were horrified by what they saw.”

Officers said they spoke to three men in their 20s and 30s but no formal allegation was made and no one was arrested.

Thomson has kept a low profile since the original allegations emerged.

A source close to the MP told the Record: “Ross will fully co-operate with any parliamentary inquiry. It would be inappropriate for him to comment at this time.”

In his original denial of the February 5 incident, Thomson said: “A series of allegations have been made against me that have featured in the media. I would like to state these allegations from anonymous sources are completely false.

“No complaint has been made to the police, Parliament or the ­Conservative Party. Nevertheless, in the interests of openness and ­transparency, I am referring myself to the Conservative Party’s disciplinary panel of the code of conduct.”

The Scots Conservatives said they could not comment as the internal party investigation is ongoing.

If the party panel concludes that further investigation is required, the matter will be referred to a QC who would be expected to report back in six weeks.

The original allegations about the MP’s behaviour were described as “completely unacceptable” by acting Scottish Conservative leader Jackson Carlaw.

The Parliamentary Standards Commission does not comment on live investigations or even confirm that they are ongoing.

If the commissioner were to hold an inquiry and find a rules breach, she would report it to the Standards Committee, which decides on ­sanctions and can recommend ­expulsion in the most serious cases.
