Britain reported 5,341 new cases of COVID-19 on Sunday, up 68% from a week ago, and 4 more deaths within 28 days of a positive test.
Government data also showed 40,333,231 people had now received their first vaccination and 27,661,353 had been given two doses.
The new COVID-19 variant, also known as the Delta variant, is 40% more transmissible than the Kent (Alpha) strain, the health secretary said, leaving the easing of social distancing in the balance for the original target date.
