Calls to create a 24/7 "Tesco NHS" are ridiculous, according to the leader of the British Medical Association (BMA).
NHS England has highlighted figures that showd if the same standard of care could be provided seven days a week, more than 4,400 lives could be saved each year.
Talking at the BMA conference in Edinburgh on Monday, Dr Mark Porter said it was simply not possible when the health service could "barely afford its current model".
