A parliamentary researcher who was arrested last year on suspicion of spying for China has been charged along with another man with espionage offences.

Christopher Cash, 29, who had enjoyed access to parliament through his work for an organisation set up by Conservative MPs, is to appear in court on Friday after he and Christopher Berry, 32, were charged under the Official Secrets Act.

The men are accused of providing prejudicial information to a foreign state, China, the Crown Prosecution Service (CPS) said in a statement on Monday.

Police arrested the two men on 13 March 2023 at addresses in Oxfordshire and Edinburgh as part of an investigation. They were subsequently released on bail and will appear at Westminster magistrates court on Friday.
