Budget leak error was ‘worst failure in OBR’s 15-year history’ - how it happened
OBR chair issues apology for Budget leak blunder
The Office for Budget Responsibility (OBR) mistakenly released its Economic and Fiscal Outlook (EFO) report almost an hour before the Chancellor delivered her Budget.
This significant blunder, containing sensitive forecasts, prompted an immediate investigation by OBR chair Richard Hughes.
The OBR described the incident as 'the worst failure in the 15-year history of the OBR,' acknowledging it was seriously disruptive to the Chancellor.
The report was intended for publication alongside the Treasury’s explanatory Red Book at the conclusion of the Chancellor's speech.
Despite the leak, Chancellor Rachel Reeves has publicly maintained her support for Richard Hughes and the OBR.
