"I am surprised and disappointed that you have chosen to repeat the figure of £350m per week, in connection with the amount that might be available for extra public spending when we leave the European Union.
This confuses gross and net contributions. It also assumes that payments currently made to the UK by the EU, including for example for the support of agriculture and scientific research, will not be paid by the UK government when we leave.
It is a clear misuse of official statistics."
Sir David Norgrove, head of the UK Statistics Authority, delivers a smart slap to Boris Johnson's wrist for resurrecting the erroneous claim that the UK pays £350m to the EU every week.
