Cells and showers have also been adapted to accommodate inmates with mobility problems.

One third of the 850 adult male prisoners in HMP Frankland in County Durham is over 50 and more than a third have disabilities.

“Smaller items such as walking frames, thermal underwear, wedge pillows and chair raisers are also provided on request,” the report from the prison’s independent monitoring board said.

It added: “It is pleasing to note that a stairlift to enable prisoners with mobility issues to access library and education facilities has now been installed and is in use.”

A “quiet wing” for old inmates has also been established and staff are planning a “grey forum” to assist prisoners over 50 deal with their concerns over health and physical activities.
