Prison violence and A&E waiting times

5 live Investigates takes a look behind bars via a series of leaked prison incident reports from a five day period in January this year. With over a hundred incidents, prison officers and staff question whether safety can be assured. And the number of central call outs to control instability; so called 'Gold Command Incidents' have also been steadily rising over the last 3 years. Ex prisoners and their families say levels of violence are unprecedented.The programme also reveals, for the first time, the full extent of long waits in accident and emergency departments in England. New figures obtained from the Health and Social Care Information Centre, reveal how many patients spent more than 12 hours in casualty in the last three years. The devolved nations of the UK already regularly publish this information, but the NHS in England does not. What do the figures show about the state of our emergency departments?
