A 24-year-old Royal Navy sailor appeared at Westminster Magistrates' Court in London on Thursday, accused of spying for Russia. Teddy Young faces two charges under the UK's National Security Act for allegedly obtaining and preparing to share protected information between November 2024 and May 2025, according to London's Metropolitan Police Service.
The Crown Prosecution Service (CPS) outlined the allegations in a summary: while serving as a Royal Navy warfare intelligence rating with high-level security clearance and access to intelligence systems, Young allegedly accessed and retained sensitive UK defense and intelligence material. He is also accused of engaging in activity consistent with preparing to pass that information to a foreign power.
Prosecutors say Young used the dark web to try to contact Russian authorities, drafting a message that “sought to make contact with a potential threat actor.” The court heard that he was not asked to enter a plea due to the seriousness of the charges. He will remain in custody until his next appearance at the same court on 16 October.
Background and arrest
Young joined the Royal Navy in April 2024 and is accused of committing the offences during his first deployment, which began on 4 November 2024. He was previously arrested on 21 May 2025 and released on bail pending further investigation. At that time, his security clearance was suspended and he was removed from his duties.
The Royal Navy issued a statement acknowledging the arrest of a service member, but declined to comment further while the legal process is ongoing. The case has drawn attention to the broader security challenges facing the UK and its allies, particularly in light of EU sanctions expansion and concerns about hybrid threats.
This incident comes amid heightened scrutiny of Russian espionage activities across Europe. In recent months, several European countries have reported attempts by Russian intelligence to recruit insiders or exploit vulnerabilities in defense establishments. The UK's National Security Act, introduced in 2023, provides a modern legal framework to counter such threats, replacing outdated espionage laws.
Legal experts note that cases like this underscore the importance of robust vetting and monitoring of personnel with access to sensitive information. The UK's Ministry of Defence has not disclosed the specific nature of the material allegedly compromised, but the CPS summary indicates it involved “sensitive UK defense and intelligence material.”
Young's next court appearance is scheduled for 16 October, where he may be asked to enter a plea. If convicted, he could face a lengthy prison sentence under the National Security Act, which carries penalties of up to life imprisonment for the most serious offences.
The case has also raised questions about the effectiveness of security protocols within the Royal Navy, especially for new recruits. Young's alleged activities occurred during his first deployment, suggesting that even relatively junior personnel may have access to highly sensitive information.
As the legal proceedings continue, the UK's intelligence community will likely review its procedures to prevent similar incidents. The case also serves as a reminder of the persistent threat posed by foreign intelligence services, a concern echoed across the continent as European nations bolster their defenses against espionage and Russian military adaptations.
