Another 393 people have died after contracting coronavirus – taking the UK total to 1,808.
The latest increase is a sharp increase from yesterday’s rise of 180.
:: England – 367 deaths, bringing total to 1,651
:: Scotland – 13 deaths, bringing total to 60
:: Wales – seven deaths, bringing total to 69
:: Northern Ireland – six deaths, bringing total to 28
The government has said there are now 25,150 confirmed cases of coronavirus in the UK.
In England, a further 367 people who tested positive for coronavirus have died, bringing the total number to 1,651.
The patients were aged between 19 and 98 years old and all but 28 of them had underlying health conditions.
The 19-year-old victim did not have underlying health conditions, NHS England said.
In Scotland, 1,993 people had tested positive for the virus as of 9am on Tuesday, up 430 on the previous day.
Nicola Sturgeon said the sharp rise was partly because 108 of these positive tests came from a lab which was unable to submit data over the weekend.
There have been 112 new confirmed cases of coronavirus in Wales, bringing the total number to 1,563.
Dr Giri Shankar, incident director for the novel coronavirus (COVID-19) outbreak response at Public Health Wales, said the true number of cases is likely to be higher.
It should be noted that while today’s number of cases is lower than numbers previously reported, this should not automatically be considered a trend as case numbers can be subject to daily fluctuation, he said.
Testing in Northern Ireland has resulted in 53 new positive cases, with the total number of confirmed cases in the region now at 586.
It comes as new figures suggest the true toll of coronavirus-related deaths across the country is higher than reports from hospitals suggest.
Data from the Office for National Statistics (ONS) for England and Wales shows there were 24% more deaths relating to the virus up to and including 20 March, compared to hospital-only data for the same period.
Earlier, Boris Johnson chaired a meeting of his cabinet by videolink as he continues to self-isolate in 11 Downing Street after testing positive for coronavirus.
He used the meeting to tell his ministers: The situation is going to get worse before it gets better – but it will get better.
Mr Johnson also stressed the rising number of coronavirus deaths in recent days showed the importance of Britons sticking to social distancing rules, Number 10 added.
There are more than 800,000 global infections and more than 38,000 deaths worldwide.
The World Health Organisation warned that while attention has shifted to epicentres in western Europe and North America, COVID-19 epidemics are far from over in Asia and the Pacific.
