Sir Julian Lewis: The Government seem to be keen to maximise the gravity of the OBR’s accidental leak while minimising the gravity of the Chancellor’s deliberate leaks. The Minister has twice frankly admitted not being aware of the case of Labour Chancellor Hugh Dalton, who resigned for inadvertently leaking to a journalist a single sentence of his 1947 Budget moments before it was due to be announced. Now that he has understood what actually happened then and that that was the paradigm case, does he think it holds any lessons or examples of conduct that the Chancellor ought to consider following?

[The Chief Secretary to the Treasury (James Murray): I came here this morning expecting to be critiqued by the Opposition for their view of Government policy; I did not expect a critique of my knowledge of history, but that appears to be the route that the right hon. Gentleman wants to take. When I gave way to the right hon. Member for Gainsborough (Sir Edward Leigh) yesterday, my right hon. Friend the Health Secretary said I was being too generous, and I am inclined to agree with him.

On the broader point just made by the right hon. Member for New Forest East (Sir Julian Lewis), I think we need to be really careful about downplaying the seriousness of the OBR publishing its forecast early. It is not a “narrow matter”, as the right hon. Member for Salisbury (John Glen) said; we cannot simply brush it away. This is a serious leak of highly sensitive information, and we take it very seriously as a Government.]
