Speculation continues to mount as the chancellor prepares to deliver what is likely to be the last Budget before the general election on Wednesday 6 March. Most of that speculation has so far focused on tax cuts, although both Jeremy Hunt and Rishi Sunak have been less keen to talk up the prospect of further tax reductions after official forecasts were reported to have reduced the amount of “headroom” available to meet their fiscal rules. The main question has been whether Mr Hunt will cut income tax or repeat the national insurance cut he introduced in last year’s autumn statement, with either offering a pre-election giveaway to voters.
