Several of the report's observations are worth noting down — not least that advance briefing of the Budget is "corrosive of good government," and that "almost all the evidence received [about the government's Enterprise Zones] is unsure about the extent to which they will contribute to UK growth." But more significant is the suggestion that both the Treasury and the Office for Budget Responsibility could do more to accommodate each other when it comes to constructing growth forecasts. The problem is that some of Osborne's measures — such as the extra cut in corporation tax — were decided on so late that the OBR couldn't, apparently, factor them into their calculations. As the report puts it, rather drily:
"The Treasury now has to deal with an external and independent body in constructing the Budget. It needs to make allowances for that. However, the timetable agreed for this forecast and Budget required all decisions which would impact on the economic forecast to be made at least a fortnight before Budget day. We recommend that the timetable should be revisited to provide more flexibility enabling economic shocks and late political decisions to be accommodated. It is understandable that a number of adjustments to the process and timetable will be needed, given that this was the first full forecast cycle since the creation of the OBR."
