The UK has reported 6,634 new coronavirus cases - the highest daily total ever recorded.
A further 40 people are reported to have died within 28 days of testing positive for COVID-19, official figures show. The last time the daily death toll was higher than 40 was on 14 July, when 44 deaths were recorded.
All of the deaths happened in England, apart from two in Scotland and one in Wales.
England recorded the vast majority of Thursday's coronavirus cases - 5,632 - followed by Scotland with 465 infections, Wales with 348 and Northern Ireland with 189.
The numbers take the seven-day rolling average for cases to 4,964 - up from 3,354 last Thursday.
Despite the record amount of cases, the UK is still nowhere near a realistic comparison to the peak of April and May, when Imperial College researchers have suggested there were more than 100,000 new infections a day.
Many of these cases would have been missed at the time as more consistent community testing began in May.
The latest numbers come as Chancellor Rishi Sunak unveiled a new scheme to support wages and avoid a winter jobs crisis.
Although he admitted some will still face an uncertain future, the plan will top up wages for staff working as little as a third of their normal hours.
Designed to save roles that will be "viable" in the long-term, the scheme will start in November.
