Today’s reports about the confident noises coming from Hillary Clinton’s camp made me think about the reports I picked up about how confident David Cameron was about the EU referendum on voting day.

The MPs I spoke to, who had been out campaigning in the field, seemed to agree: after all this fuss, Brexit would all blow over. By lunchtime on polling day, the bookmakers put the odds of Leave at 15pc; they would later sink to 7pc. The noises that I picked up – that noises pretty much everyone in my trade
