Royal Navy sailor charged with spying for unnamed foreign power under National Security Act

A serving Royal Navy member has been charged with espionage offences after an investigation into allegations that he obtained sensitive material intended to benefit an unidentified foreign state. The suspect, named as 24-year-old Teddy Young from Bedfordshire, faces accusations brought under the National Security Act (NSA), legislation that was introduced to modernise the way the United Kingdom prosecutes threats posed by hostile states and intelligence activity.

The charges were announced by police, who said Young had been taken into custody and remanded pending his first court appearance. He is scheduled to appear before Westminster Magistrates' Court on Thursday. The case is significant because it involves a member of the armed forces — a category of suspect whose access to classified material makes allegations of this kind particularly sensitive for national security planners and military leadership alike.

According to the details released by investigators, one of the allegations concerns the obtaining of protected information that could have benefited a foreign power that has not been named. A further allegation relates to conduct said to have been carried out "in preparation for committing an offence of disclosing protected information," a charge that sits squarely within the powers granted by the National Security Act.

The alleged conduct is said to have spanned a period of almost six months, from 26 November 2024 to 21 May 2025. Prosecutors allege that during that window Young "obtained, copied, recorded or retained protected information," with the intention that his actions would benefit a foreign power. The charge also asserts that he knew, or ought reasonably to have known given other matters known to him, that the conduct was prejudicial to the safety or interests of the United Kingdom.

Young was arrested at his home address in Bedfordshire on Tuesday, and the speed with which charges followed suggests that the investigation had been substantially developed before officers moved. Counter-terrorism officers led the inquiry, reflecting the elevated threat that suspected state-linked activity is now treated as carrying within the British policing framework.

Cdr Helen Flanagan, Head of Counter-Terrorism Policing London, emphasised the gravity of the allegations. "These are very serious charges against a serving member of the armed forces," she said, a deliberate framing that underlines both the rank-and-file status of the accused and the trust placed in personnel who handle protected material on a daily basis.

Cdr Flanagan also revealed that the investigation had been conducted jointly with colleagues inside the Ministry of Defence. "We have worked extremely closely with relevant operational colleagues within the Ministry of Defence as our investigation has progressed to ensure appropriate measures could be taken to mitigate any potential risks linked to this matter," she said. The wording implies that authorities believed there was a live risk to be managed while the probe ran its course, and that steps were taken to contain any damage.

Police were keen to draw a clear line between this case and a separate recent matter, stating that the charges are not connected to the RAF Fairford incident. That clarification will be read as an attempt to prevent speculation that the two episodes are part of a single pattern of security failures at military sites.

The Royal Navy confirmed that one of its own had been charged but declined to go further. A service spokesperson said that, because legal proceedings are now underway, it would be inappropriate to comment in detail at this stage — a standard holding position that preserves the integrity of the forthcoming prosecution.

For the Ministry of Defence and the wider armed forces, the case raises difficult questions about vetting, monitoring and the handling of protected information by junior personnel. Allegations that a serving member may have acted for a foreign power tend to prompt internal reviews of how access to sensitive data is granted, logged and revoked, particularly where the alleged activity is said to have continued over a matter of months.

The National Security Act, under which Young has been charged, was designed to close gaps that critics argued existed in older legislation when it came to espionage, foreign interference and the protection of official information. Its use in this prosecution will be watched closely by legal commentators, not least because the definitions of "protected information" and benefit to a "foreign power" carry substantial implications for how future cases are argued.

Court proceedings have not yet begun in earnest, and Young has not entered any plea. He is remanded in custody, meaning he will remain held until his appearance at Westminster Magistrates' Court. Any subsequent decision on whether the matter proceeds to the Crown Court would be a matter for the legal process rather than police or the Navy.

Both Counter-Terrorism Policing and the Ministry of Defence have indicated that they will say little more while the case is sub judice. For now, the public record consists of the charges, the dates of the alleged conduct and the assurances of officials that risks have been assessed and mitigated. The next substantive development is expected on Thursday, when the court will consider the case for the first time.
