And once again, you seem to insist you know more about the situation and data reporting in the UK than people in the UK, because you've looked on Google and seen a few tweets.
The definition of a covid-related death, as used in all UK data, is when someone has had a positive test in the preceding 28 days. This applies to pretty much everything, including our data dashboard, PHE data, and the government report you're frantically posting screenshots from.
If someone suffers a stroke, or a heart attack, or has cancer, or anything, and tests positive for covid (or in this case, specifically the Delta variant) in the preceding 28 days, it will be counted in these figures. So if they were taken to hospital because they were dying, but picked it up while in hospital before death, they would count in this data.
Personally, I think the majority of the deaths showing up in that table will be actually be a result of covid. Possibly the overwhelming majority. But we don't know for certain, because of the definitions we use, and that there has to be a cut off somewhere.
Heck, if you won't believe me or the other posters who've tried to tell you this, try this:
That's Meaghan Kali. She's an epidemiologist for Public Health England, and one of the people who actually produces the report each week that you're screenshotting.
