A decision on whether to close an emergency department at a major hospital was being driven by the "wrong priorities" Labour leader Ed Miliband has said.
Mr Miliband said decisions in the health service should be based on "clinical judgments not by cost judgments".
He told ITV1's Daybreak: "I hope they'll save the A&E in Lewisham because I think it's very important for people there and I think we've seen a huge groundswell of people in Lewisham who are really concerned about what's happening there.
"But I think it's part of a wider problem we have in the health service under this government.
"I think you've got to take the nurses, the doctors, the patient groups with you, not fight against them, which is what we've seen so far."
The Government was accused of "breaking up" the NHS after announcing a downgrading of Lewisham A&E and maternity services
An A&E department and maternity services at a major hospital will be downgraded, Health Secretary Jeremy Hunt told MPs.
The proposed closure of units at Lewisham Hospital is part of a radical plan to rescue a neighbouring NHS trust from bankruptcy.
