OBR: Resignation of Chair

Perran Moon Excerpts

Wednesday 3rd December 2025 Commons Chamber

[James Murray]

As will be clear, I agree with the right hon. Gentleman’s remarks about Richard Hughes’s contribution to public service. However, I disagree that the premature publication of the forecast last Wednesday was a narrow matter. The report showed that it was about not simply a single error, but more systemic issues, which it highlighted, so I disagree with the characterisation of that as narrow.

The right hon. Gentleman referred to some of Professor Miles’s comments at the Treasury Committee. Professor Miles confirmed that the £4 billion headroom identified in the forecast on 31 October was not inconsistent with the sentiment that this is a very challenging fiscal position.

The right hon. Gentleman also asked about the OBR’s letter, the nature of its being published and what it speaks about for the future. As I said earlier, the publication of the OBR letter was agreed to by the Chancellor due to the unique nature of this Budget and the context of the OBR’s productivity review, as it said itself, while acknowledging that it would not become usual practice, due to the importance of preserving a private space for discussion.

The OBR leak was deeply disturbing, particularly in the light of international sensitivities. Can the Chief Secretary rule out foreign actors exploiting the OBR’s inadequate security at any point?

[James Murray]

The OBR’s report into the premature publication of its forecast found no evidence of hostile cyber-activity, but it looked at the spring forecast and identified what happened there. Concerningly, it identified that there had also been premature access to the forecast at that fiscal event. The report did not look further back at, for instance, the Chancellor’s first Budget last year or Budgets delivered by Conservative Chancellors under the previous Government. That is why it is so important that the Government take forward the report’s recommendation to conduct a forensic examination of potential premature access at previous fiscal events.

[Dr Scott Arthur (Edinburgh South West) (Lab)]

I find it rather curious that Conservative Members have a lot to say about Hugh Dalton’s Budget in 1947, but so little to say about Liz Truss’s Budget in 2022.

[Perran Moon]

Selective amnesia.

[Dr Arthur]

Exactly. It is very curious.

All the staff in my office diligently followed Mr Speaker’s advice on cyber-security and the threat of foreign intervention in our IT, and it is right that we take these matters seriously. However, based on the reports we have seen, I am not convinced that the OBR had taken the same kinds of steps to protect its own systems. Were the OBR and other Government Departments and agencies offered this advice but just did not follow it, or has there been an oversight in how we are managing security right across Government?
