Welcome to HMP Belmarsh with Ross Kemp

Ross explores how staff cope with high-profile inmates, extremists and common criminals living side-by-side and goes inside the High Security Unit, where he meets Muhammad Asif Hafeez, known as Sultan, the alleged mastermind of a drug-smuggling empire.

Ross Kemp's report from inside the maximum-security jail takes him to Belmarsh's jail-within-a-jail, where anti-Isis or anti-Islamic inmates have to be separated from Islamic prisoners for fear of reprisals. He also heads to the prison healthcare unit, and meets transgender prisoner Claire Darbyshire, who was given one of the lowest minimum terms for murder in British legal history after killing her father.
