A strike by thousands of junior doctors has been called off, the Government and the British Medical Association (BMA) have announced.
The strike, scheduled for Tuesday, has already caused major disruption as over 4,000 patients have already had their operations cancelled.
An outline agreement is thought to have been reached following four days of talks between the BMA, NHS Employers and a repsentative of the Department of Health.
All three strikes planned by the BMA have been suspended so talks can continue.
A spokesman for the Advisory, Conciliation and Arbitration Service (Acas), which has been mediating the talks, said: "Following five days of productive talks under the auspices of Acas, the BMA, NHS Employers and the Department of Health have reached an agreement.
"Acas is pleased that the talks have been held in a constructive manner and cooperative spirit between the parties, that will allow an improvement in industrial relations."
