One remark from the Christmas party season knocks insistently around my head. It came from Nigel Farage on a staircase in the Ritz. For those who didn’t enjoy 2016, a year of political revolution, he gleefully promised: ‘2017 will be a hell of a sight worse.’ My, my. What did he mean? Had he taken one Ferrero Rocher too many? Or does Farage, like an increasing number of MPs, expect a general election next year, including further dramatic upsets? The biggest reason for pooh-poohing a 2017 election isn’t the Fixed-term Parliaments Act but Prime Minister’s character.
