A COBRA meeting will be held on Sunday to discuss financial assistance for businesses and contingency planning for vital public services brought to their knees by staff absences.
On Saturday 90,418 lab-confirmed Covid-19 cases were recorded on Saturday, the second highest figure on record.
A total of 900 people were admitted to hospital, bringing the weekly total to 6,056 – and 125 died within 28 days of testing positive for the disease.
