23 year old Daniel Khalife is accused of collecting and sharing sensitive information with foreign agents over more than two years between May 2019 and January 2022 after joining the army just before his 17th birthday.
The court heard that months into his first post with the Royal Signals, based at Beacon Barracks, in Stafford, he offered to stay in the military for more than 25 years and do what they asked.
He contacted MI6 saying he wanted to be a “double agent” and later told police his contact with the Iranians was all a double bluff, a jury has been told.
Reporter Rachel Venables is outside court with more information.
The trial continues.
