The ONS datasets that you may find 'interesting' are published here:
https://www.ons.gov.uk/peoplepopula...nalfiguresondeathsregisteredinenglandandwales
Note that they are for England and Wales only (other sets are published for Scotland and NI). The datasets are in xlxs spreadsheet form.
They are provisional for the current year, updated every Tuesday, 11 days in arrears.
I am awaiting the next release to make observations, the significant numbers of deaths with Covid-19 will be reflected more in Tuesday's figures.
The current year dataset also compares each week with an average of the deaths occurring in the equivalent weeks for the previous 5 years.
As to the bank 'holiday' weekend, I would not want to see the current shopping patterns disrupted by wholesale Supermarket closures and I would expect that the Supermarkets themselves would not want that either.
