Hospitals in England declare 'major incidents'
The government has "betrayed patients", Labour leader Ed Miliband says, as the political row over the problems facing A&E units deepens.
Data for the last three months showed waiting times in England had dropped to their worst levels for a decade.
In the first prime minister's questions of 2015, Mr Miliband said the government's policies were the cause, but David Cameron hit back saying Labour was using the NHS as a "political football".
