The £17bn difference reflects somewhat lower expected GDP growth in our projections, and a significantly smaller rise in the ratio of income tax and corporation tax receipts relative to GDP than projected by the Treasury.

The Treasury would still be able to claim that its golden rule of borrowing only to invest would just about be met on average over the current economic cycle, but only by a very narrow margin based on our projections. Looking ahead to the next economic cycle, the picture is far less rosy.
