Coronavirus: Dodgy data and double counting - the UK's testing data is a mess

Testing - doing it well, accounting for it well and using the results sensibly - is clearly a crucial part of the solution. Yet here in Britain we don't know how many people have been tested for the disease. Indeed, while the government was up until recently producing numbers on people tested, it recently admitted those figures are suspect and will have to be revised. This is only one of the issues the Statistics Authority has with the government, as covered in a highly critical letter from its head, Sir David Norgrove, to Health Secretary Matt Hancock.
