Navy investigating after report emerges that documents about the workings of HMS Anson were found in a Wetherspoons pub in Cumbria

The Royal Navy is set to investigate after official documents about one of its £1.3bn “hunter killer” submarines were reportedly found in the toilets of a Wetherspoons pub.

Files carrying details about the HMS Anson were left in the Furness Railway in Cumbria, the Sun reported. The documents showed the inner workings of the nuclear-powered submarine and were used by submariners learning how to isolate and depressurise elements of its system.
