Our thanks to Paul for this. The start of the article:

Barnardo’s says male prisoners are being denied visits from their children either as punishment or because they have not ‘earned’ right.

Thousands of children are being denied visiting rights to see their fathers in prison because of changes to the prison discipline system, according to a report.

The report, Locked Out, by the children’s charity Barnardo’s, says 17,000 children a month visit a parent in prison, and changes to the incentives and earned privileges (IEP) scheme mean that prison visits are being used as a way to enforce discipline.

The new regime has resulted in male prisoners being denied visits from their children, either as a punishment or because they have not “earned” the right. The report estimates that there are 200,000 children with a parent in jail.

The rules do not apply to women’s prisons, [my emphasis] where official guidance explicitly states that children of prisoners should not be penalised in effect for their mother’s actions.
