Britain’s MI5 warned members of Parliament that spies from China, Russia and Iran are targeting UK politicians in an effort to influence policy, gather intelligence and undermine democracy, Reuters reported on Monday.
MI5 Director General Ken McCallum urged lawmakers to stay alert to blackmail attempts, phishing attacks,and approaches from individuals seeking to cultivate long-term relationships or make donations to sway decisions.
“When foreign states steal vital UK information or manipulate our democratic processes, they don’t just damage our security in the short term—they erode the foundations of our sovereignty,” McCallum said, mentioning the three countries.
Iran’s inclusion alongside Russia and China highlights growing concern over Tehran’s global network of influence operations, which British and European officials say increasingly target lawmakers, journalists and activists.
MI5’s warning follows reports linking Iranian cyber groups to intimidation and disinformation campaigns abroad, including against UK-based journalists critical of the Islamic Republic.
The advisory comes a week after prosecutors dropped a high-profile espionage case against two British men accused of spying for China, after the government declined to present classified evidence in court. The case has sparked debate over how to confront foreign interference while protecting intelligence sources.
McCallum concluded his message by urging vigilance among lawmakers: “Take action today to protect democracy—and yourself.”
