Wales, Northern Ireland and Scotland have their own health services and collect their own data.
This smells of trying to cook the books yet again - for quite some time, the death totals for England haven't been collected on the same basis as in other parts of the UK, and have at points in the past tended to be underestimates in comparison.

Daily updates on English Covid-19 deaths paused amid accuracy concerns
Daily updates on the coronavirus death toll in England have been paused amid growing concern that the numbers could have been exaggerated.
A message on the governments website on Saturday said: Currently the daily deaths measure counts all people who have tested positive for coronavirus and since died, with no cut-off between time of testing and date of death.
