Mark Bullen's British nationality has been revoked over security reasons, the Daily Mail has reported

A former British police officer who has been living in Russia for more than a decade has been stripped of UK citizenship after being deemed a security threat, according to the Daily Mail.

Mark Bullen, who worked for Hertfordshire Police for eleven years, received a letter from the Home Office last October informing him that his UK nationality had been revoked on "national security" grounds, the outlet said in an article earlier this week.

According to Bullen, the decision by the British authorities left him "completely shocked."

"I absolutely deny I am any threat to the UK. I find that comical... I am certain it is an overreaction. I have no idea why they targeted me," the 45-year-old said, who permanently moved to Russia in 2014 and currently does social media for Zenit St Petersburg football club.

The former policeman said it was "hard to believe that a country like England, which is supposed to be about freedom and liberty, would behave in this way."

Bullen was previously detained at Luton Airport when he arrived in Britain to visit his relatives in November 2024.

"I was questioned for four hours under the Terrorism Act," he recalled.

The former policemen said that his DNA and fingerprints were taken before he was released without any charges.

He became a Russian citizen in 2022 and said that he currently has no plans to return to the UK.

"Initially, I was worried but once the dust settled, I felt OK... I live in Russia, my family is here, I have four children, we have quite a good lifestyle," he explained.

In September 2025, veteran British politician George Galloway said he was detained along with his wife and interrogated by police for several hours at a London airport after their return from Russia. RT's Lebanon bureau chief, Steve Sweeney, also faced similar questioning under the Terrorism Act after landing in the British capital last July.
