The Speaker of the Commons has said that the decision to drop the charges against two men accused of spying for China could leave parliament vulnerable to espionage.

Christopher Berry and Christopher Cash were charged under the Official Secrets act, after they were accused of gathering and providing information prejudicial to the safety and interests of the state between 28 December 2021 and 3 February 2023.

Sir Lindsay Hoyle told the Times that he took the security of the house "incredibly seriously" and was considering launching a private action against the pair.

Mr Berry and Mr Cash have previously denied the charges, and Beijing has called the allegations "malicious slander".

The Crown Prosecution Service's (CPS) decision has been criticised by the Home Office, who said it was "disappointing that they will not face trial given the seriousness of the allegations".
