Tell us something we don't know.
Ms Harman was criticised for claiming men earn 23 per cent more than women while the Office for National Statistics puts the figure at less than 13 per cent.
A source said Ms Harman's department was warned about using the figure beforehand but went ahead anyway.
Sir Michael Scholar, head of the UK Statistics Authority, has now written to Ms Harman warning she had been potentially misleading and could "undermine public trust in official statistics".
I hate to be the one to tell you, Sir Michael, but that trust sailed away on the HMS Disgust a few years ago.
"It is the Statistics Authority's view that the use of the 23 per cent on its own, without qualification, risks giving a misleading quantification of the gender pay gap."
Sir Michael, they didn't 'risk' giving a misleading figure, they 'intended' it. It's what Labour do.
