Never have expectations from the Budget on 29 October been so high and never have the chancellor’s influence over events which will affect his forecasts been so low.

How on earth can Philip Hammond possibly be expected to make judgements about the economy when its performance depends on the political manoeuvres behind Brexit negotiations which shift from one week to the next? How can he commit to long-term spending on local government, on social care, education and health without knowing the likelihood of the tax revenues flowing into fund it? He must regret switching the Budget and the Autumn Statement; a March 2019 Budget at least would have a clearer idea of what Brexit deal has been decided. Indeed rather than focus on the Budget Hammond may already have decided it is the Spring Statement which is likely to be more accurate.
