The UK has the fifth-highest toll globally - after the United States, Brazil, India and Mexico - and reported a further 1,631 deaths and 20,089 new cases on Tuesday, with critics accusing the government of an apparent slow initial response to the COVID-19 crisis.
According to data compiled by BBC News, the United Kingdom has the fifth-highest number of deaths in the world, behind the US, Brazil, India and Mexico.
The 100,162 deaths are more than Britain's civilian toll in World War Two and twice the number killed in the 1940-41 Blitz bombing campaign.
Britain's Prime Minister Boris Johnson holds a vial of the Oxford-AstraZeneca coronavirus vaccine, during a visit to Barnet FC's ground at the Hive, which is being used as a coronavirus vaccination center, in London, Monday, Jan. 25, 2021.
In England, 7,162 Covid-19 deaths are now known to have taken place between January 16 and 24, with 203 in Wales and 157 in Northern Ireland.
An ashen-faced Prime Minister Boris Johnson told a news conference just minutes after the official statistics were published that it was "hard to compute" the loss felt by families across the UK.
A year on, hundreds of thousands of Britons are grieving the loss of loved ones, and demanding an accounting for the awful toll.
But decisions during the pandemic also played a part. Johnson's Conservative government is accused by many scientists of waiting too long to impose a lockdown in March as infections were rising exponentially. "Decisions to enter lockdown have consistently come late, with the government failing to learn from past mistakes or the experiences of other countries". "The virus is still spreading and we're seeing over 3,500 people per day being admitted into hospital", he added.
The Office for National Statistics (ONS) data released today (Tuesday) records the number of deaths involving coronavirus, based on any mention of Covid-19 on the death certificate in the week ending January 15, with the death registered up to January 23.
