A letter was sent last month by a large group of senior civil servants to the MoD’s permanent secretary alongside anonymised testimonies in which women described their personal experiences.

The accounts included claims that women had been “propositioned”, “groped” and “touched repeatedly” by male colleagues at the MoD in a workplace culture the civil servants said was “hostile to women as equal and respected partners”.

In the letter, which is marked “official-sensitive”, the group of “senior civilian women” said their “day-to-day professional lives are made difficult thanks to behaviours that would be considered toxic and inappropriate in public life, but that are tolerated at the MoD”.
