Nigel Farage has failed to commit to banning trans women from female prisons after his new justice adviser said they should not be automatically barred.

Vanessa Frake, a former prison governor who oversaw the detention of Rose West, said decisions on where to house inmates should be made on an ‘individual basis’.

Asked for his views on her comments yesterday, the Reform UK leader told the Daily Mail: ‘I’ve personally never worked in a prison so I can’t answer [the question] but I think you’ll find that the answer that you’ll get from somebody who has worked in prisons at the highest possible level is, I think, basically it’s about risk assessment, isn’t it?

‘But in terms of the problems in prisons, it’s a relatively small one.’

A Reform spokesman later added of Ms Frake: ‘An ex-prison governor... has a different opinion. That does not constitute party policy.’
