Hospital hold-ups delay East of England ambulances
A BBC investigation has shown that ambulances often face severe delays because of pressure on A&E departments.
Dr Pamela Crispin, of the East Anglian Ambulance Service, said that at a hospital in the region on one day last week 6% of patients waited for more than an hour to be offloaded from the ambulance.
There will be a full report on Inside Out in the East at 19:30 GMT on Monday on BBC1 and it will be available on the iPlayer for seven days.
