After spending his first night on HMP Wandsworth’s induction wing, the 51-year-old is believed to have been moved onto the prison’s Vulnerable Person’s wing.

The unit is commonly home to prisoners at high risk of harm, including paedophiles, sex offenders and police informants, with notoriously poor conditions and “inhumane” cell standards.

The prison source warned Brand could soon be “approached soon by a couple of prisoners who rule over the wing” and may be forced to “line their pockets in order to have a slightly safer and more comfortable time”.

Brand’s celebrity lifestyle has been firmly left outside the prison gates, with the actor now forced to wash his clothes in a small sink and dry them on a small heated pipe running through his cell.
