LONDON - Britain's coronavirus death toll has gone up by 621 to 4,934 - including 29 patients who did not have any underlying health conditions.
Public Health England reported an extra 555 deaths in England, Public Health Wales recorded 12 in Wales and there have been 7 in Northern Ireland.
The level of infections has risen sharply by 5,903 to 47,806 - the largest daily increase yet - dashing hopes that the rate of people getting the disease could be starting to plateau.
The Department of Health also said that, as of 9am on Sunday, a total of 195,524 people have been tested, up from 183,190 the previous day. 
NHS England gave the breakdown by region of the 555 deaths of patients inEngland: - East of England 40 - London 174 - Midlands 74 - North East & Yorkshire 103 - North West 47 - South East 81 - South West 36.
They also said of the deaths in England, the patients were aged between 33 years and 103 years old, with 29 of the 555, aged between 35 and 95 years old, having no known underlying health condition.
It comes amid concerns a huge backlog of potential patients awaiting their results could mean infections are far higher than is being reported.
If the backlog for processing the tests is too great, the rate of infections will remain at roughly the same level, with the services already pushed to the brink and only able to carry out a certain number of tests per day.
Matthew Lesh, head of research at the Adam Smith Institute, told MailOnline: 'The UK numbers are masked by the inability of the laboratories.'
