The UK now has the highest number of coronavirus deaths in Europe, according to the latest government figures.
There have been 29,427 deaths recorded across the UK - a figure Foreign Secretary Dominic Raab said was "a massive tragedy".
The latest total for Italy, previously the highest in Europe, now stands at 29,315.
But experts say it could be months before full global comparisons can be made.
Both Italy and the UK record the deaths of people who have tested positive for coronavirus, BBC head of statistics Robert Cuffe said, but Britain has reached this figure "faster" in its epidemic than Italy.
He said there are caveats in making such a comparison, including the UK population being about 10% larger than Italy's, while Britain's largest city is three times bigger than Italy's.
Each country also has different testing regimes with Italy conducting more tests than the UK to date.
In the last 24 hours, the UK government has recorded another 693 deaths.
Speaking at the daily coronavirus briefing, Mr Raab said the 29,427 lives lost was "a massive tragedy" the country has "never seen before... on this scale, in this way".
But he would not be drawn on international comparisons, saying: "I don't think we will get a real verdict on how well countries have done until the pandemic is over, and particularly until we get comprehensive international data on all cause mortality."
This is a sobering moment. Italy was the first part of Europe to see cases rise rapidly and the scenes of hospitals being overwhelmed was met with shock and disbelief.
But we should be careful how we interpret the figures.
On the face of it both countries now count deaths in a similar way, including both in hospitals and the community.
But there are other factors to consider.
First the UK has a slightly larger population. If you count cases per head of population, Italy still comes out worse - although only just.
Cases are confirmed by tests - and the amount of testing carried out varies.
The geographical spread looks quite different too - half of the deaths in Italy have happened in Lombardy.
In the UK, by comparison, they have been much more spread out. Less than a fifth have happened in London, which has a similar population to Lombardy.
Then, how do you factor in the indirect impact from things such as people not getting care for other conditions?
The fairest way to judge the impact in terms of fatalities is to look at excess mortality - the numbers dying above what would normally happen.
You need to do this over time. It will be months, perhaps even years, before we can really say who has the highest death toll.
Meanwhile, the personal stories of those who have died are still emerging. They include three members of the same family who died within weeks of each other after contracting the virus.
Keith Dunnington, 54, a nurse for more than 30 years, died at his parents home in South Shields on 19 April. His mother Lillian, 81, died on 1 May and her husband Maurice, 85, died days later.
Meanwhile, Momudou Dibba, a house-keeper at Watford Hospital who went "above and beyond" in his job, died with the virus on 29 April.
In a statement, West Hertfordshire NHS Trust said Mr Dibba, known as Mo, was "kind, caring and considerate".
Meanwhile, 14 people from the same care home in Northern Ireland have died from Covid-19 related symptoms.
There have now been 1,383,842 tests for coronavirus across the UK, including 84,806 tests yesterday, Mr Raab told the No 10 briefing.
For the third day in a row the government has failed to hit its target of 100,000 daily tests, according to the BBC's Reality Check team.
Health Secretary Matt Hancock set the target at the beginning of April and the government announced on Friday and Saturday that it had hit the 100,000-plus mark.
New data published by the Office for National Statistics (ONS), shows that by 24 April there were 27,300 deaths where coronavirus is mentioned on the death certificate.
Including deaths reported to the ONS since 24 April, it brings the total number to more than 32,000.
These figures can also include cases where a doctor suspects the individual was infected, but a test was not carried out. The daily government figures rely on confirmed cases.
The ONS data goes up to 24 April - delays in reporting and completing death certificates means it lags behind the daily figures.
