Yes the prisoners would come from all over U.K. to one prison and likely be far away from family and friends so not much visiting, but I don’t see any way around that other than to use video calling technologies.
I disagree in that I think if the women, who probably shouldn’t be in prison anyway, have children or any family near by, they must be able to be visited by them. The children need to see and touch their mothers (unless they are dangerous).
To deport mothers away from their families would be a worse crime by the state than whatever crime they had committed ( unless Myra Hindley type).
I do think Trans prisoners need their own safe sections.
At the same time women need their own sex-based prison space.
What did the Equalities Commission say about this recently? Is it or is it not law that women must be housed according to their sex?
