I am sure I remember reading that "Karen" White had sexually assaulted female prison officers although it is not mentioned in the summary here:

Then there is Andrew Burns / Tiffany Scott (aka Obi Wan Kenobi/Mighty Almighty)
"a violent male who identifies as a trans woman, is a serial violent offender with a string of convictions for violence against women (including members of the public, nurses and prison officers), assaults, stalking, criminal damage, vandalism, making false allegations against prison officers and resisting arrest."

It was in that case, or maybe another one in Scotland, that there is a little bell ringing in my brain about female prison officers making complaints about being sexually assaulted but then being persuaded to drop their complaints.
If Rory Stewart is telling the truth and has not "misspoken" then my first question to him would be,
"You say that while you were Prisons Minister you were aware that female prison officers had been raped by male inmates. Yet you said and did nothing. Why did you cover this up?"
