PRISONERS at a Surrey prison are having to use buckets as toilets in their cells because of “unacceptable” sanitation standards, inspectors reported today.

The stench is so bad that some inmates at HMP Coldingley are choosing to dispose of their excrement by throwing it out of the window.

It marks a return to the days of “slopping out,” a practice which was meant to have been outlawed in 1996 after an insurrection at Strangeways prison in Manchester.
