Doctors back a seven-day NHS service but want the government to outline how they will fund and staff it.
Chair of the British Medical Association Dr Paul Flynn said: "There is clear public support for more weekend services, but no clear plan on how this will be delivered.
“At a time when the NHS is facing a £22 billion funding shortfall, many hospitals are in the red and weekday services are under strain.
"The government must explain how they plan to expand services by up to 40% across the week.
"How will they pay for it? How will they ensure there isn’t a reduction in mid-week services? How will they put in place the support doctors need to deliver the same high standard of care over seven days?"
