A giveaway Budget in March preceding a general election in May against an improving economic backdrop: that, we’re told, is Downing Street’s favoured scenario. But still the election is Keir Starmer’s to lose, so here’s my start-the-year advice to him. Don’t bang on about Rishi Sunak being too rich; don’t make immigration the issue, because you have no solutions; don’t pretend to admire Margaret Thatcher; but do channel John Major – to whom you bear much closer comparison – and offer a new Citizen’s Charter.
