Office for Budget Responsibility
The question
To ask the Chancellor of the Exchequer, what recent assessment her Department has made of the effectiveness of the Office for Budget Responsibility.
Answered by Lucy Rigby
The Office for Budget Responsibility (OBR) is the UK’s independent forecaster and the Government is fully committed to the OBR’s independence and its vital role as a core part of our fiscal framework. That is why one of the first Acts of this Parliament introduced the fiscal lock so that the OBR could never be sidelined.
On 26 November 2025, the OBR’s Economic and Fiscal Outlook was accessed prematurely ahead of the Budget. The OBR’s investigation into this incident was published on 1 December. HM Treasury will work closely with the OBR to ensure robust security arrangements are in place for all future forecasts.
