Rishi Sunak and Health Secretary Steve Barclay have been accused of going into hiding while the NHS teeters on the brink of collapse.
Downing Street said Mr Sunak didn't have immediate plans to visit hospitals or publicly address the spiralling pressures on the crisis-hit health service after dire scenes on the wards over Christmas.
Health chief Mr Barclay is also not scheduled to visit medics battling on the frontline at present - although a source said he was in constant contact with NHS leaders.
