HAS Scottish Tory MP Ross Thomson gone rogue? He is seemingly working unofficially on trade deals with the Japanese government.

The enthusiastic Brexiteer, who represents Aberdeen South at Westminster, has teamed up with two other members of Jacob Rees-Mogg’s right-wing European Research Group on a trip to the Land of the Rising Sun.

A series of tweets showed Thomson, along with fellow Tory MPs Ranil Jayawardena and Chris Green, meeting a number of mid-level Japanese politicians.

Thomson arrived in Tokyo yesterday, telling his social media followers that he was “looking forward to discussing the opportunities for our post Brexit trading relationship, closer cooperation on security and the potential to strengthen links with Aberdeen on energy, innovation and technology”.

He met with Yasushi Masaki, the director general of the European Affairs Bureau at the Ministry of Foreign Affairs and “discussed Brexit, Trade, economic issues, immigration and our different political systems amongst so much more”.

Thomson also reported that he had had an “insightful breakfast” with Yasutoshi Nishimura, the influential deputy chief cabinet secretary in President Shinzo Abe’s Liberal Democrat party.

The Tory MPs also met Daisaku Hiraki, Japan’s parliamentary vice-minister of economy, trade and industry, to “talk about the new future trading relationship between the U.K. and Japan,” according to Thomson.

He added: “We also discussed the U.K. joining the TPP. He is also extremely keen to visit #Aberdeen!”

It’s understood Thomson and the others were invited by the Japanese Embassy.

A Tory source told The National: “The focus of the trip is mostly on trade and economic links. There has also been promotion of links to universities, such as Robert Gordon in Ross’s constituency.”

Earlier this year Thomson caused a diplomatic incident during a trip to Iraq when he made light of Saddam Hussein’s brutal regime.

An SNP source said: “Ross Thomson might think he’s important by playing at trade deal talks across the world – but the reality is if people like him are representing the UK abroad in any shape or form then we should all be worried.”

The Japanese embassy did not respond to requests for a comment.
