The most senior doctor in NHS England has said he was "personally terrified" that hospitals could have been overwhelmed in the early stages of the pandemic.
Prof Sir Stephen Powis told the Covid inquiry officials had drawn up a draft document advising whose care should be prioritised if the NHS found itself unable to cope with the surge in patients.
The 'Covid-19 decision tool' assigned points based on a patient's age, frailty and underlying conditions. A high score meant they might not be admitted to intensive care if services were overwhelmed.
The tool was never issued publicly, after it became clear infections might have already reached a peak in March 2020.
