More than 160 people have now tested positive for coronavirus in the UK, in the largest day-on-day increase.
In total, 163 people had tested positive for Covid-19 as of 9am on Friday, up from 115 cases reported at the same time on Thursday.
Northern Ireland then confirmed its fourth case later on Friday, bringing the total to 164.
It comes as the PA news agency understands that samples taken from an elderly patient who died at Milton Keynes Hospital are currently being investigated for coronavirus.
Health Secretary Matt Hancock appeared to suggest the patient, reportedly an 88-year-old man, did have the illness.
But NHS England said it could not confirm the patient had coronavirus and was still awaiting test results.
On Thursday evening another patient, reported to be a woman in her 70s, became the first person in the UK to die after being diagnosed with Covid-19 while at the Royal Berkshire Hospital in Reading.

He sought to reassure the public following panic-buying in some areas, with supermarkets seeing their shelves cleared of essentials such as toilet roll and paracetamol.
Speaking on BBC’s Question Time, Mr Hancock said: “The Government has supplies of the key things that are needed, and, within the food supply, we are absolutely confident that there won’t be a problem there.
“And, crucially, we are working to makes sure that if people are self-isolating, they will be able to get the food and supplies that they need.”
He said there was “absolutely no need” for individual people “to go round buying more than they need.”
One supermarket executive told the BBC sales of basics such as pasta and tinned goods had “gone through the roof”, adding: “While I think people don’t need to panic buy and should just shop normally, I’m not sure the Government can guarantee all food supply in all instances.”
However Environment Secretary George Eustice said he has been reassured by retailers that they are taking “all the necessary steps to ensure consumers have the food and supplies they need”.
New blog posts from Public Health England (PHE) suggested people may need to get supplies for loved ones in future if social-distancing measures are brought in and more people are told to stay at home.
The posts urged people to “plan ahead”, adding: “Everyone has a part to play, and we’re asking people to think about what they do in a typical week, how they could limit contact with others if asked to, and how they could help people in their community who might need support if certain social-distancing measures were put in place.
“This might include helping older relatives and neighbours to get some food in, so that they would have supplies for a week or so if required, ensuring someone would be available to go shopping for them, or arranging for online delivery if they needed it.”
