Business Secretary Grant Shapps has said he is concerned that the planned strike by ambulance staff on Monday will put lives at risk.
Thousands of nurses and ambulance staff in England are due to strike in what many predict will be the biggest strike day the NHS has ever seen.
Mr Shapps said the Royal College of Nursing (RCN) has “very responsibly” told the NHS about where they will be striking and therefore enabled emergency cover to be put in place, but claimed ambulance unions have not provided such information.
