Women in the Submarine Services suffered misogyny, bullying and other unacceptable behaviours, a Royal Navy investigation has found.

A report published on Friday found these behaviours “amongst all ranks and rates in the past”, although said “this is not pervasive across the entire Submarine Service”.

The head of the Navy, First Sea Lord Admiral Sir Ben Key, said he was “truly sorry” and that such behaviour was “intolerable”.

The two-year-long investigation was ordered in October 2022, following allegations by a former member of the Royal Navy. The allegations dealt with in the report spanned from 2014 to 2020.
