Hospital appointments will be cancelled today as junior doctors take strike action in a row over new contracts.
The strike by the British Medical Association (BMA) involves all junior doctors except those on call to provide emergency cover.
Hospital bosses said letters had been sent to patients whose appointments were at risk of being cancelled.
Patients who have not received a letter are advised to attend their appointments as normal.
The BMA fears that health secretary Jeremy Hunt could impose the new junior doctor contracts despite concerns it will lead to pay cuts and unsafe working hours.
Last-minute talks were being held yesterday to try and avoid today’s strike going ahead.
More than 2,800 routine operations have been cancelled in preparation for today’s action.
