supermax

Mr Fairhurst has also called for American "Supermax"-style rules imposed on the UK's most dangerous inmates.

The Trump administration has deported 17 more alleged gang members to El Salvador, the US state department said Monday, despite legal battles over removing people to the Central American country's supermax prison.

Criticism of the deportation of the Venezuelans to the supermax prison has been growing not just in the US and in their homeland but also in El Salvador.

He believes that, at the very least, the men should be placed in some kind of immigration centre ahead of an eventual return to Venezuela rather than in a supermax facility designed for hardened Salvadoran gang members.

Delgado may never be released, but inmates having jobs in prison is one of the reasons why Estelle Supermax Penitentiary is appealing to the UK government.
