The Conservative Party dropped two potential candidates to become MPs after MI5 warned they could be Chinese spies, it has been reported.
It comes as ministers continue to face questions about allegations of espionage in Westminster after the arrest of a parliamentary researcher on suspicion of spying for Beijing.
The Times said the security service advised the Tory Party in 2021 and 2022 that the two MP hopefuls should not be included on the central list of candidates.
The newspaper cited an unnamed source as saying: “It was made very clear that they posed a risk.
“They were subsequently blocked from the candidates list. They weren’t told why.”
A Conservative Party spokesman told the paper: “When we receive credible information regarding security concerns over potential candidates we act upon them.”
The claims will fuel debates about the UK’s relationship with China following the arrest of the staffer under the Official Secrets Act.
The Briton was arrested along with another man by officers on March 13 on suspicion of spying for Beijing, it was revealed by the Sunday Times.
Officers from the Metropolitan Police’s Counter Terrorism Command, which oversees espionage-related offences, are investigating.
One of the men, in his 30s, was detained in Oxfordshire on March 13, while the other, in his 20s, was arrested in Edinburgh, Scotland Yard said.
Both were held on suspicion of offences under Section 1 of the Official Secrets Act 1911, which punishes offences that are said to be “prejudicial to the safety or interests of the state”.
They have been bailed until early October.
The arrests were only revealed at the weekend and the researcher at the centre of the row had links with senior Tories including security minister Tom Tugendhat and Foreign Affairs Committee chairwoman Alicia Kearns.
The allegations have led to increased pressure from China “hawks” on the Tory benches for Prime Minister Rishi Sunak to toughen his stance towards Beijing.
