We can reveal that a CHINA espionage suspect was at a summit with European leaders in the weeks before his arrest.
The news could spark a diplomatic row with Britain’s allies over exactly how much influence the 20-something parliamentary researcher might have wielded.
Insiders said the arrest was likely the “tip of the iceberg” and that a spy ring could be operating in Westminster.
Now experts say the arrest should be a “wake-up call” for Britain.
The senior parliamentary adviser, who we are not naming, was arrested in March under the Official Secrets Act.
He firmly denies allegations of espionage.
Weeks earlier, he was a keynote speaker on relations with China at a London conference.
High-ranking German politicians and leading German bankers also spoke.
Sinan Selen – the deputy of the German secret service MI5 – also spoke via Zoom.
Westminster insiders said they suspected a larger network of Chinese spies and sympathizers had penetrated Whitehall.
An intelligence insider said: “China takes espionage seriously. He will be the tip of the iceberg.”
Former Tory leader Iain Duncan Smith – who says Chinese agents have previously impersonated him in emails – said: “The government must urgently change UK policy before it is too late.”
