OBR: Resignation of Chair

John Glen Excerpts

Wednesday 3rd December 2025 Commons Chamber

[James Murray]

I very much agree with the sentiment of my hon. Friend’s question. The OBR is a vital part of our fiscal framework—indeed, as I mentioned earlier, one of the first acts we took on entering government was to strengthen its role to ensure that it could never be sidelined. It is precisely because we see the OBR as holding such an important place in our fiscal framework that it is important that we maintain its integrity and trust.

My hon. Friend asks what further steps the OBR will take. We will work with the National Cyber Security Centre and the OBR to take forward the recommendation that a forensic examination of potential premature access at previous fiscal events is carried out. Let me add that there is no evidence of hostile cyber-activity, but the OBR report’s findings indicated access at previous fiscal events. That is a very serious matter that we will investigate.

[John Glen (Salisbury) (Con)]

Richard Hughes was a first-rate public servant, but he did the right thing on the narrow matter of the premature upload of the file last week. OBR representatives told us a number of things yesterday in the Treasury Committee. They told us that there was a £16 billion downgrade and £4.2 billion of headroom on 31 October, because there were also improved tax revenues. I do not think £4.2 billion can be characterised as a black hole, but it was a challenging circumstance—that is the truth. Will the Minister consider, in all future Budgets, that such a letter should be made available, at the same time that Budget publications and OBR publications are made available, setting out what was said to the Chancellor at what point? We could then verify whether the press conference on 4 November was very wide of the mark and gave a materially misleading view of what was actually happening.

[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.
