Britain on Tuesday reported zero daily deaths from Covid-19 for the first time since July 30 last year despite a recent rise in cases linked to the Delta variant.
According to the latest government figures, 127,782 people in the UK have died within 28 days of a positive test since the start of the pandemic — the worst death toll in any European country.
The UK has had 4.49 million cases in total.
Tuesday's zero daily deaths came after the government reported just one Covid death across the UK on Monday, a public holiday.
Official death figures are typically lower at weekends and holidays because of a lag in reporting.
The milestone comes after Britain moved forward with plans in recent months to unlock its economy.
The government imposed a tough lockdown in January during a second wave of cases and deaths that followed the emergence of a more transmissible variant.
The UK was one of the first nations in the world to begin a mass innoculation campaign.
Since the rollout in December, it has administered two doses of vaccine to more than 25 million people — almost half the adult population.
Experts have warned, however, that Britain could face a third wave of cases driven by the Delta variant of concern first identified in India.
On Tuesday, Britain recorded over 3,000 coronavirus cases for the seventh straight day, putting in doubt plans by Prime Minister Boris Johnson's government to completely lift restrictions on June 21.
"We will continue to assess and monitor the data daily," a UK government spokesman said, adding that the roadmap for removing Covid measures was "based on data, not dates".
Last week, Johnson said there was nothing in current data that suggested England's roadmap would have to be delayed.
