If 12,000 have died in hospital, and 6,000 in care homes, I'm no mathematician but I'd say the vast majority are not dying in Hospital, around a third are dying in care homes and are not being included in the daily death totals the Govt is peddling, you can see why they'd like to omit them.
Because these are people dying who are in 'end of life care' for other illnesses.
So again it comes down to establishing what the course of death is.
