Labour's Shadow Health Secretary Andy Burnham said the decision by the British Medical Association to go on strike showed the strength of feeling against the Government's pension reforms.
However he urged but doctors to "pull back" from taking any action that could impact patient care.
This result reflects the clear strength of feeling in the profession at the arrogance of a Government attacking public services from every angle.
It's the BMA's right to make their own decision, but even at this stage I would urge doctors to pull back from any form of action that damages patient care, including disruption to non-urgent care.
Instead, I would urge the BMA to follow other routes in making clear the substance of their disagreement with the Government.
How will the industrial action planned for June 21 affect you?
Doctors will turn up at work as usual. They will handle all emergency and urgent cases. So what kind of strike is it?
Doctors are to take industrial action for 24 hours in protest at the Government's controversial pension reforms.
