Office for Budget Responsibility Forecasts

John Glen Excerpts

Monday 1st December 2025 Commons Chamber

[James Murray]

My hon. Friend is absolutely right: imagine if I were trying to defend a Budget to the House that was delivered with just a few billion pounds of headroom—what message would that send about the UK economy? The headroom is there to reduce the cost of Government borrowing and to give us protection against future shocks that might come our way.

[John Glen (Salisbury) (Con)]

On the process failure of the premature publication of the document, I think there is consensus across the House that it is damaging to the reputations of the UK, the OBR and the Treasury. I welcome the fact that the report says there are issues for the Cabinet Office, the Treasury and the OBR in respect of how documents are hosted. However, on the substantive issue of what the OBR had told the Treasury and the net overall effect of that, there can be no doubt. There may be a dispute about whether £4.2 billion was sufficient or not, but we know for certain that the OBR did not say there was a significant black hole that required a 2p increase in income tax, which was the consequence of the Chancellor’s press conference. Does the Chief Secretary agree that the material distinction between those two issues must not be lost, and that he must face up to the reality of the overall net effect and the impression that was left?

[James Murray]

The right hon. Gentleman is a former Treasury Minister, so he will know the importance of the OBR’s productivity downgrade and the impact that that has had on the forecasts. He will know that £16 billion is a significant downgrade to have had as a result of that productivity review, and he will know that were I here defending a Budget with just a few billion pounds of headroom, that would not be a position that any of us would want to be in.
