Watch ITV News Science Editor Tom Clarke's analysis of the rise in cases
There have been 33,470 new cases of Covid-19 in the UK in the past 24 hours - the highest daily figure since the outbreak began.
The results, as of 9am on Thursday, bring the total number of cases in the UK to 1,290,195.
There have also been 563 new deaths reported, which puts the total figure at 50,928.
Separate figures published by the UK’s statistics agencies for deaths when Covid-19 has been mentioned on the death certificate, together with additional data on deaths that have occurred in recent days, show there have been more than 65,000 deaths involving coronavirus in the UK.
Experts have previously warned that describing the daily figure as a record could be “misleading” as it is not clear how many people were actually infected during the height of the first wave, due to a lack of community testing at the time.
On Monday, there was a significant jump in Covid cases in the UK, which is not believed to have been linked to mass testing in Liverpool.
What's behind Thursday's huge surge in cases?
ITV News' resident statistician, Prof Jennifer Rogers, vice president at the Royal Statistical Society, said it is too early to tell if this a trend or a one-off spike.
She said: "Looking at case numbers by specimen date, it looks like the spike really happened on Monday and then the numbers have come back down. There’s a difference between specimen date and reporting date.
"At the moment it’s too early to see if it’s a blip or part of a new trend. Everything else regarding growth and R number has been suggesting that things are levelling off and even potentially starting to shrink.
"I would be very surprised if this is the start of something to worry about. Sometimes we get these types of spikes in time series data, and one day of spike isn’t enough to say whether it’s a new trend. Looking at Liverpool’s data, it doesn’t look like it’s due to them. "In short, I’m not worried just yet. And we can’t really say statements like this is the highest ever number because we already know that figures in the first wave would probably be even higher than we see now if we’d been testing back then like we are now.
