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 Britain reached this figure faster in its epidemic than Italy.
But he said there are caveats in making such a comparison, including the UK population being about 10% larger than Italy’s.
Each country also has different testing regimes, with Italy conducting more tests than the UK to date.
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.”
Prof Sir David Spiegelhalter, of the University of Cambridge, said we can be “certain” that all reported figures are “substantial underestimates” of the true number who have died with the virus.
He said: “We can safely say that none of these countries are doing well, but this is not Eurovision and it is pointless to try and rank them.”
He added the “only sensible comparison is by looking at excess all-cause mortality, adjusted for the age distribution of the country” [but] “even then it will be very difficult to ascribe the reasons for any differences.”
