A report by the National Audit Office (NAO) has admitted that it knows next to nothing about the cash, which is not being used for transactions or identified as savings held by UK households." Any guesses what happened to it? Could it have been spent on cash in hand jobs undertaken by furloughed workers? Spent on drugs during lockdown? Stashed away in mattresses in case there's a financial crash when Brexit kicks in next year, or saved to have ready to buy black market goods rather than starve after 1/1/21?
