One in 10 people arriving at major A&E departments in England are having to wait more than 12 hours before being admitted, transferred or discharged, new figures show.
At some NHS trusts the figure is close to one in five, while at two trusts - East Kent and Barking, Havering & Redbridge - the proportion is higher than one in four.
It is the first time data has been published that measures waits of more than 12 hours from the point of arrival at A&E, and comes as the overall waiting list for treatment in England has climbed to a new record high.
