In his moment of triumph in the Commons, Boris Johnson played it straight. There was little of the harrumphing, or the silly classical quips, or the poor taste jokes we are used to. Only his hair – flipping up and outwards – refused to behave.

Here was the often jelly-like Boris with a spine: he looked as though he could smell the victory coming his way. It was clear from the word go of his opening speech on Wednesday morning ahead of the debate and historic vote in the Commons on Britain’s departure from the European Union that he was finally onto a winner.
