Royal Navy sailor faces court over alleged attempt to spy for Russia

What happened

Royal Navy intelligence specialist Teddy Young appeared at Westminster magistrates’ court in London on 8 October 2026, accused of attempting to supply military secrets to Russia, The Guardian reported.

The 24-year-old allegedly used his security clearance to obtain classified defence and intelligence material following deployment aboard a warship. He is also accused of seeking direct contact with Russian authorities and preparing a Russian-language message containing information he intended to share.

The Crown Prosecution Service set out allegations covering 26 November 2024 to 21 May 2025. These concern preparations to disclose protected information, as well as obtaining, copying, recording or keeping such material with the intention of benefiting a foreign power.

The Metropolitan police said Young had been charged under the National Security Act following an investigation led by Counter Terrorism Policing London. Officers arrested him at his Bedfordshire home on 6 October.

At the hearing, Young confirmed his personal details, including his address in Clapham, near Bedford. He did not seek bail and was remanded in custody. The charges remain allegations, not findings of guilt.

The background

Young had previously been arrested in May 2025. According to The Guardian, he was then suspended from his duties and remained on gardening leave until the latest arrest.

The newspaper reported that he is the first person serving in Britain’s armed forces to face charges under the National Security Act 2023. That makes the proceedings a first for the military under this legislation, rather than evidence of any established pattern of offending within the service.

The alleged misuse of security clearance is central to the case. Clearance allows personnel to handle sensitive information for authorised work; an insider-risk concern arises when someone is suspected of using that trusted position for another purpose.

A separate US case illustrates a related concern involving access to defence information. In an earlier report on a DIA employee accused of attempting to transfer classified material, US prosecutors alleged that an IT specialist tried to give information to an FBI agent posing as a foreign official. The allegations and legal proceedings in that case are distinct from Young’s.

The Guardian’s account does not identify the warship or describe the classified material in detail. It reports an alleged attempt to pass information, without establishing that Russian authorities received it.

What people are saying

Commander Helen Flanagan, who leads Counter Terrorism Policing London, described the allegations against a serving military member as serious. She said investigators had worked closely with operational counterparts in the Ministry of Defence so that measures could be taken to reduce any associated risks.

A Royal Navy spokesperson confirmed that the charges followed the counter-terrorism police investigation. The service declined to discuss the matter further while court proceedings continued.

District Judge Annabel Pilling said the information before her gave substantial grounds to believe Young might avoid returning to court and commit further offences if released. Although no bail application had been made, she indicated that she would refuse one.

The Guardian also reported that the case was separate from the recent investigation into an incident at RAF Fairford.

What happens next

Young is due to appear before a specialist judge at the Old Bailey on 16 October. He will remain in custody ahead of that hearing.

The source report gives no trial date or account of a plea. Whether the alleged handling of information and preparations for disclosure amounted to criminal offences remains a matter for the court.
