A junior Royal Navy sailor, Able Seaman Teddy Young, has appeared in court accused of preparing to spy for Russia. The 24-year-old, who specialized in warfare intelligence, was charged under the National Security Act 2023 at Westminster Magistrates' Court on Thursday.

Young is alleged to have retained UK defence and intelligence material accessible through his role and made preparations to disclose sensitive information. The charges, which cover the period between November 26, 2024, and May 21, 2025, are the first of their kind against a member of the armed forces under the new legislation. The BBC understands that the allegations include translating a message into Russian and searching for a web portal to submit information to Russia.

Appearing in court wearing a grey police-issue sweatshirt, Young confirmed his personal details. He faces charges of engaging in conduct in preparation for disclosing protected information and obtaining, copying, recording, or retaining protected information, with the intent to benefit a foreign power. The alleged offences are not connected to a recent incident near RAF Fairford that led to several arrests.

Commander Helen Flanagan, Head of Counter Terrorism Policing London, stated that these are "very serious charges" against a serving member of the armed forces. She highlighted close collaboration with the Ministry of Defence to mitigate potential risks. A Royal Navy spokesperson confirmed the charge but declined further comment due to ongoing legal proceedings.

The National Security Act 2023, which came into effect in July 2023, aims to update espionage laws and provide authorities with stronger tools to counter threats from foreign states. It broadens the scope of offenses related to aiding foreign powers and covers acts of espionage, sabotage, and interference.

Young was arrested at his home in Bedfordshire on Tuesday. He was remanded in custody by Judge Annabel Pilling and is scheduled to next appear at the Old Bailey on October 16. The case marks a significant early test for the recently enacted security legislation.

This development underscores ongoing concerns about foreign state interference and espionage, particularly in sensitive sectors like defense and intelligence. The specific nature of the alleged preparatory acts, such as translation and online searches, suggests a methodical approach to gathering and potentially transmitting classified information.

Experts have noted that the National Security Act was designed to address evolving threats in the digital age, allowing for prosecution of individuals who engage in activities that could compromise national security, even if direct disclosure has not yet occurred. The charges against Young reflect this proactive stance by authorities.
