The UK government also confirmed a further seven deaths among patients who died within 28 days of testing positive for the virus.

The latest figures come as Health Secretary Matt Hancock confirmed the Delta variant now represents 91% of new cases in the UK.
The health secretary was questioned over allegations made by the Prime Minister's former aide Dominic Cummings to the Health and Social Care Committee and Science and Technology Committee.
Mr Hancock has said the current data shows the Delta variant, which was first identified in India, is now responsible for the majority of positive Covid cases in the UK.
Mr Hancock told MPs this number was from an assessment he saw "last night".
His comments come just a week after Public Health England warned there is early evidence to suggest there is a "significantly increased risk of hospitalisation" from the Delta variant in comparison to the Alpha strain.
