A Royal Marine assigned to a unit responsible for guarding the UK’s nuclear deterrent has been questioned by counterterrorism police over his alleged links to neo-Nazi ideology. The marine, whose identity remains undisclosed, was referred to the Prevent counter-extremism programme and subsequently questioned after a troubling incident that raised concerns within the Ministry of Defence.
The controversy began several months ago when the marine reportedly circulated a survey within his unit. The survey asked colleagues if they were concerned that diversity, equality, and inclusion policies were undermining the strength and integrity of the Corps. The survey was removed within 24 hours, but the incident prompted an internal investigation. According to a source from the Ministry of Defence, it was discovered that the marine had connections to a neo-Nazi political party.
The marine’s actions were taken seriously, leading to his referral to Prevent, a government-led initiative designed to prevent radicalisation and stop individuals from becoming involved in terrorism. The marine was questioned by police in connection with his controversial views, although no terrorism-related charges have been brought against him.
Sources familiar with the investigation tell The Times, which first reported the story, that the marine serves in 43 Commando unit, a core component of the Royal Navy tasked with securing the UK’s nuclear deterrent. The unit maintains round-the-clock surveillance to safeguard the nuclear submarines and their weapons, a mission that demands the highest levels of discipline and security.
In a video posted online, the marine expressed his frustration with the investigation, claiming that the actions taken against him were unjust. “We believe we have the high standards that we keep for a very important reason, which is to prevent marines from being killed in dangerous situations when we go to war,” he said, adding that he was concerned these standards were being compromised. He also questioned the legality of his detention under the Terrorism Act, asking, “Am I expected to commit any acts of terrorism?”
The Ministry of Defence (MoD) has since suspended the marine’s security clearance, and he has been ordered to work from home instead of his usual post at the Faslane naval base, where he had recently been assigned a clerical role. A defence source also revealed that his social media posts, which were described as a “rant” that contradicted military standards, are under further investigation.
The MoD has denied any claims of positive discrimination in its diversity and inclusion policies. It pointed out that the rigorous physical standards required to earn the coveted green beret have not changed, and no woman has yet met the criteria for this elite status.
An MoD spokesperson said: “Royal Marine Commando selection standards haven’t changed, and the same high standards apply to every recruit. This issue is subject to an ongoing investigation, so we’re unable to comment further at this stage. We expect the highest standards of all our service personnel and are committed to investigating any allegation of behaviour that could bring the armed forces into disrepute.”
