The Budget bombshells revealed

An interesting spat is just breaking out over cuts. The Conservatives have a leak from the working of the Budget showing detailed projections in government revenue to 2013-14 covered by all the main Sundays. This suggests income tax rising from £140bn this year to £191bn in four years’ time. The Tories say this is not explained by economic growth and that the gap – £15bn – is equivalent to 3p in the basic rate of income tax. Liam Byrne is pushing back, saying Osborne is trying to “mislead the British people” (as if the government would try to do such a thing) and that the increase was accounted for “the economy returning to growth, no more, no less”.

At first, I was a suspicious of the Tory analysis: income tax does tend to rise faster than the economy recovers in a typical post-recession, just as it falls more sharply in the downturn.
