Christopher Berry, 32, and Christopher Cash, 29, are accused of an offence under the Official Secrets Act.
Two men have been charged with spying for China after an investigation by counter-terrorism police.
Christopher Berry, 32, from Witney in Oxfordshire, and Christopher Cash, 29, from Whitechapel in east London, are both accused of an offence under the Official Secrets Act, the Metropolitan Police said.
It is alleged that between December 2021 and February 2023 Berry “for a purpose prejudicial to the safety or interests of the State, obtained, collected, recorded, published or communicated to any other person articles, notes, documents or information which were calculated to be, might be, or were intended to be, directly or indirectly, useful to an enemy”.
Cash is accused of the same offence between January 2022 and February 2023.
Commander Dominic Murphy, head of the Counter Terrorism Command, said: “This has been an extremely complex investigation into what are very serious allegations.
“We’ve worked closely with the Crown Prosecution Service as our investigation has progressed and this has led to the two men being charged today.
“We’re aware there has been a degree of public and media interest in this case, but we would ask others to refrain from any further comment or speculation, so that the criminal justice process can now run its course.”
