The Royal Navy is investigating reports that a submarine commander allegedly flouted social distancing guidelines by throwing a party at HMNB Devonport.
Footage has emerged of the HMS Trenchant crew enjoying the gathering after docking for repairs at the Plymouth naval base.
The nuclear-powered attack submarine had been at sea for months on manoeuvres.
The video was shared by Forces Compare - a website search engine that specialises in comparing quotes from military insurance specialists.
The crew are thought to have been at sea for many months and returned to a very different UK than they left. With the latest Covid restrictions the crew were faced with isolation when returning home to port.
It is understood that the Trenchant’s captain has been sent home on leave following the party, which apparently took place despite him having been advised that lockdown regulations would make such a gathering inappropriate.
An investigation is underway. It would be inappropriate to comment further.
Two lower-ranking seamen are also believed to have been disciplined for refusing to comply with an order from a senior naval base officer who told them to end the party.
