Accident and emergency departments in England are understaffed on average by nearly 10%, a BBC survey suggests.
A Freedom of Information request by BBC 5 live revealed 101 out of 166 hospital trusts who responded had 1,260 vacant posts as of August 2013.
The largest proportion of vacancies were found in four trusts in London.
According to the BBC, the Department of Health said A&E staffing was an ongoing problem, but action was being taken.
