Prisoners and detainees say they are sweltering for up to 23 hours a day in poorly ventilated cells with no way of cooling down as the UK faces its hottest day on record.
It has even been alleged that officers at one jail are deliberately running the heating so that prisoners cannot get comfortable, something that the MoJ has staunchly denied, while one man in immigration detention said his room had no ventilation or air conditioning.
“The headaches and dehydration caused by the heat can be intense,” said Kevan Thakrar, a prisoner in HMP Belmarsh.
