The UK has reported 30,501 new COVID-19 cases, with a further 316 deaths within 28 days of a positive test.
That now brings the total number of people who have died after testing positive for COVID-19 in the UK to 70,752 and the total number of cases to 2,288,345.
It compares to yesterday's increases of 34,693 confirmed coronavirus cases and 210 related deaths.
But the true number is likely to be higher as Scotland is not releasing death data between 25 and 28 December, while Northern Ireland is not providing figures on cases or deaths over this period.
A further 231 people who tested positive for coronavirus have died in hospital in England, bringing the total number of confirmed deaths reported in hospitals to 48,542.
NHS England said the patients were aged between 30 and 103. All except five, aged between 36 and 85, had known underlying health conditions.
The deaths were between 9 December and Boxing Day.
There were 10 other deaths reported with no positive COVID-19 test result.
Officials in Wales said there had been a further 4,142 cases of coronavirus, taking the total number of confirmed cases there to 139,642.
Public Health Wales reported another 70 deaths, taking the total in Wales since the start of the pandemic to 3,368.
Officials said the data was for a 48-hour period from 9am on Christmas Eve to 9am on Boxing Day.
Figures published by the UK government often do not correlate with totals from the nation-specific health bodies, due to differences in the timeframes and methods with which cases and deaths are recorded.
