The British Red Cross has stepped in to transport some patients home after they were discharged from A&E in Sheffield, where Deputy Prime Minister's Nick Clegg is an MP.
Sheffield Teaching Hospitals NHS Foundation Trust said they were currently facing an "unusual demand" and were very busy at this time.
They are using the charity to help transport patients who are fit enough to leave A&E, but the Red Cross is not providing health care to patients, the hospital's duty matron said.
Andy Peers, British Red Cross operations manager for Yorkshire said the charity had "highly trained volunteers and an extensive fleet of ambulance vehicles" that regularly help the NHS in times of high demand.

Hospitals are saying there simply are not enough beds and trained medical staff for sick patients who need to be admitted.
