The UK has recorded a further 7,143 coronavirus cases – the highest daily figure since the outbreak began.
It takes the total number of confirmed coronavirus cases in the UK to 446,156.
Experts have warned the daily record figure could be misleading as it is unclear how many people were infected during the first wave due to a lack of testing capacity in the community at the time.
The government also confirmed a further 71 people had died within 28 days of testing positive for the disease as of 9am on Tuesday.
This brings the total number of deaths in the UK to 42,072.
Government figures show the UK’s current testing capacity to be 287,690 – but only 198,402 tests were processed in the same 24 hour period.
Boris Johnson has promised to increase testing capacity to 500,000 by the end of October in a bid to suppress the spread of coronavirus.
The prime minister had also pledged to turn around coronavirus tests in 24 hours so that people were made aware of their results faster, so that swifter action could be taken when it came to tracking people who had been in contact with the virus.
Data also shows there is currently 2,049 patients in hospital with coronavirus in the UK.
At the peak of the virus, there was 17,172 people admitted in hospital with Covid-19 on April 12.
