The ex-husband of a Scottish Tory MP alleged to have groped men in a Westminster bar has said it is a “good insight into why we are no longer together”.

Ross Thomson, who represents Aberdeen South, is reported to have been escorted from Strangers’ bar in the House of Commons on Tuesday night.

Police said they were called at around 11pm following a report of “sexual touching”, but no formal allegations were made and no one was arrested. Officers confirmed they spoke to three men in their 20s and 30s.

The Scottish Tories said they are investigating the claims, adding: “We are aware of reports of an incident last night and the matter is being looked into.”

On Twitter, Mr Thomson’s former partner Douglas Mathewson said the reported behaviour was “giving everyone a truthful perception of the individual”.

He deleted one tweet stating the allegations were “a good insight into why we are no longer together”, before adding: “Removed my previous post due to the nature of some threats I was getting. All jesting was welcomed though.

“For reference, I haven't named individuals but if I were to, they would equally have to be held accountable for any actions of theirs that is in the public domain.”

He later tweeted another user: “I feel what is now in the public domain is giving everyone a truthful perception of the individual and that gives me relief because there were a lot of people who didn't believe me.”

Writing to another, Mr Mathewson said he had received threats “from people who are still behind this so-called individual”.

He added: “I believe the gravity of actions as reported in the public domain should be enough to show them what he is really like.”

He said he didn’t "buy" that stress was behind the alleged behaviour.

It comes after colleagues of Mr Thomson said they were concerned about the pressure he was under.

One Tory MP said: “I have been worried about Ross. He has been under a lot of pressure with the workload and Brexit.”

Another backbencher added: “When something like this happens, you realise how little support there is for people under stress.

“This is a very stressful place. We have to make sure MPs are looked after.”

The claims initially appeared on the Guido Fawkes political blog, which alleged Mr Thomson was drunk and removed from the pub a number of times before police were called.

The Daily Record reported there had been an all-party parliamentary beer group pub quiz earlier in the evening.

Mr Thomson is known as a “hardline” Brexiter and has previously been at the centre of a number of controversies.

In April 2018, he was criticised after joking about Saddam Hussein while on a trip to Iraq.
