London: Britain on Saturday reported 708 more deaths from COVID-19 in a new daily high, as the number of confirmed cases rose to nearly 42,000.
The health ministry said 4,313 people who tested positive for the virus in hospital had died as of 1600 GMT Friday while there were 41,903 confirmed cases as of 0800 GMT Saturday, up 3,735.
The toll has been steadily increasing at more than over 500 deaths a day this week and the country is bracing for an expected peak in the next week to 10 days.
Prime Minister Boris Johnson, who is in self-isolation after developing mild symptoms of the disease, ordered a three-week lockdown of the country on March 23 to try to cut infections.
But there has been concern that warmer weather forecast for this weekend could tempt people from their homes to green spaces and public parks.
"I just urge you not to do that," Johnson said in a video message on Friday. "Please, please stick with the guidance now."
Health Secretary Matt Hancock also warned against any relaxation in social distancing. "If we do, people will die," he told a daily briefing on the government's response on Friday.
A special address on the crisis by Queen Elizabeth II is to be broadcast on Sunday evening.
Peak in Easter
Imperial College London epidemiologist Neil Ferguson, who is advising the government, told BBC radio on Saturday a peak was expected around the Easter weekend.
"We still think things will plateau but we'll be at quite high levels of infection for weeks and weeks rather than seeing quite a rapid decline as the type seen in China," he said.
But he said that was dependent on people staying at home. If that happened, it could lead to less stringent measures in place "at least by the end of May", he added.
The announcement of another record rise in deaths came after 13 residents at a care home in Glasgow died in one week in a suspected outbreak of coronavirus.
The Burlington Court Care Home in the Cranhill area of the city said those who died had underlying medical conditions and two staff members were being treated for COVID-19.
Tests for coronavirus are currently carried out on the most serious cases that require hospital treatment, suggesting the true extent of confirmed cases and deaths is an under-estimate.
The government meanwhile announced that up to 4,000 low-risk prisoners near the end of their sentence could be release from jails in England and Wales to try to stop the spread of COVID-19.
A total of 88 prisoners and 15 prison staff have tested positive for the virus, and there is concern it could spread rapidly because of shared cells and overcrowding.
The justice ministry said those released would be electronically tagged and temporarily released on licence in stages. High-risk offenders will not be considered for early release.
