Leeds Prison is the most overcrowded in England, according to a report by the Howard League for Penal Reform.
The facility was built to hold nearly 700 prisoners, but the league’s report found the Category B site had more than 1,200 inmates at the end of January.
The charity found that 64 of the 75 Category B and Category C men’s prisons in England and Wales had more inmates than they were designed to hold.
