Advertisement Britain's daily coronavirus deaths have fallen by two-thirds in a week while cases have plunged by another 40 per cent, official figures revealed today. Department of Health bosses recorded another 2,379 positive Covid tests, with the rolling seven-day average for infections now at the lowest levels since mid-September. And 20 victims were added to the official tally, meaning the UK has now gone a fortnight without registering over 100 daily deaths. Figures today also suggested that 10 per cent of adults in Britain have now been fully vaccinated against Covid, while 60 per cent — or 31.6million — have had their first dose. The promising data came as Boris Johnson today insisted England was still on track to end lockdown by summer. He said that he couldn't 'see any reason for us to deviate from the road map', which will see all legal restrictions on social contacts abolished by June 21 as part of the final phase of the four-step route out of the crisis.
