Question to the Cabinet Office:

To ask the Chancellor of the Duchy of Lancaster and Minister for the Cabinet Office, for what reason, by what methodology, and with what data the Office for National Statistics adjusts raw data from its sample population testing for covid-19 and implements those adjustments in reporting the prevalence of covid-19 for the different regions of England.

The information requested falls under the remit of the UK Statistics Authority. I have therefore asked the Authority to respond.
