This lunchtime's BBC One News at One featured the following exchange, with the BBC's assistant political editor Norman Smith letting slip a word he ought not to have let slip:
Sophie Raworth: Let's talk to Norman Smith, who is in Westminster. Well, we've got the OECD, the international think-tank, saying that a second referendum would have a positive, a significant effect on the UK economy if it reversed Brexit. That's not a realistic option though, is it?
Norman Smith [shaking head]: Sadly not now. Mr Hammond has already said this lunchtime it's not happening and, to be honest, even the most optimistic of Remainer would probably concede it's about as likely as the Loch Ness Monster putting in a surprise appearance. At least for now.'Sadly', eh, Norman?
