There have been more than 3.5 million confirmed cases of coronavirus in the UK and more than 100,000 people have died, government figures show.
However, these figures include only people who have died within 28 days of testing positive for coronavirus.
Almost seven million people have had their first dose of a coronavirus vaccine.
The government announced 1,631 deaths within 28 days of a positive test on Tuesday, taking the overall total to just over 100,000.
More people have now died with coronavirus in the second wave than the first.
Prime Minister Boris Johnson said he was “deeply sorry” for all the lives lost and promised the nation would “come together” to honour the dead once the crisis was over.
Of the deaths announced on Tuesday, 1,520 were in England, 87 in Scotland, 16 in Northern Ireland and eight in Wales.
Chief medical officer Professor Chris Whitty said the number of deaths would come down “relatively slowly” over the next two weeks.
The average number of daily deaths began to rise again in September, following the first peak in spring last year.
Rules were amended over the summer to include deaths in the coronavirus total only if they occurred within 28 days of a positive test. Previously in England, all deaths after a positive test were included.
England has seen the majority of UK deaths from Covid-19. Using the 28-day cut-off, there have been about 88,000.
When looking at the overall death toll from coronavirus, official figures count deaths in three different ways, each giving a slightly different number.
First, government figures count people who died within 28 days of testing positive for coronavirus – and that total has now reached 100,000.
Second, ONS figures include all deaths where coronavirus was mentioned on the death certificate, even if the person had not been tested for the virus. This figure is nearly 104,000 deaths, to 15 January.
The third measure counts all deaths over and above the usual number at the time of year – that figure was more than 99,000 by 15 January.
In total there were 20,019 deaths registered in the week to 15 January, that’s about 28% above the “normal” level for the time of year.
Of that figure, 7,776 were deaths related to coronavirus – the third highest total of the pandemic.
