OBR Chair Resigns: Budget Day Leak Scandal Explained (2026)

Imagine a scenario where a critical economic forecast, meant to be revealed at a specific moment, gets leaked ahead of time. The fallout? The head of the forecasting body resigns. That's exactly what happened with the Office for Budget Responsibility (OBR) in the UK, and it's a bigger deal than you might think. Richard Hughes, the OBR's chair, stepped down following a significant error that led to the premature release of a key document on Budget day.

Hughes, in his resignation letter, took "full responsibility" for the blunder. An internal investigation revealed that this early publication was the most severe failure in the OBR's 15-year history. The market-sensitive report was accessed a whopping 43 times from 32 different devices in the hour leading up to the Chancellor's Budget speech. This is akin to giving someone the answers to a test before they even start – it completely undermines the integrity of the process.

In letters to both the Chancellor and Dame Meg Hillier, chair of the Treasury Select Committee, Hughes expressed confidence in the OBR's ability to recover by implementing the investigation's recommendations. He stated his resignation was necessary to allow the organization to move forward swiftly. He was scheduled to face questions from the Treasury Select Committee about the Budget and the OBR's economic forecasts, but this appearance was cancelled following his resignation.

Chancellor Rachel Reeves thanked Hughes for his service. However, Kemi Badenoch, a prominent Conservative Party leader, accused the Chancellor of using Hughes as a "human shield," suggesting a political dimension to the resignation. And this is the part most people miss... It's not just about a technical error; it's about accountability, trust, and the potential for political maneuvering around economic data.

Paul Johnson, former director of the Institute for Fiscal Studies, wasn't surprised by the resignation. He called it "a really bad mistake" but also acknowledged Hughes as a "very effective and very robust" leader. "I think it's a shame for Richard Hughes and a shame for the OBR," he added, highlighting the personal and institutional impact of the incident.

Hughes had recently begun his second five-year term, having been renominated in May. He initially assumed the role during the challenging times of the COVID-19 pandemic in October 2020. His background includes serving as director of fiscal policy at the Treasury and as division chief of the International Monetary Fund's fiscal affairs department for eight years, giving him a wealth of experience in economic forecasting and policy.

Adding another layer to the situation, Sir Keir Starmer defended Chancellor Reeves against accusations of misleading the public about the nation's finances before the Budget. Reeves had hinted at potential income tax increases due to gloomy economic productivity forecasts. However, the OBR later revealed that they had informed the Treasury that higher incomes would offset the productivity downgrade, boosting government tax receipts. The question is: Was this a genuine miscommunication, or something more calculated? But here's where it gets controversial... Did Reeves intentionally paint a bleaker picture to soften the blow of the actual budget, or was she genuinely relying on incomplete information?

Following the leak, Hughes brought in a cybersecurity expert to investigate how the document was prematurely published. The investigation concluded that the incident caused "heavy damage" to the OBR's reputation and was "seriously disruptive" to the Chancellor, although it was deemed inadvertent. The report emphasized that the "ultimate responsibility" lay with the OBR's leadership and labelled it the "worst failure in the 15-year history of the OBR."

The investigation also uncovered a similar incident in March, where someone gained early access to financial forecasts during Reeves' Spring Statement but didn't act on the information. The OBR's leaked forecast effectively revealed measures like a pay-per-mile charge for electric vehicles and a three-year freeze on income tax and National Insurance thresholds before the Chancellor's official announcement.

The investigation, led by Ciaran Martin, former chief executive of the National Cyber Security Centre, found no evidence of foreign actors, cyber-criminals, or internal collusion. Instead, it identified a "pre-existing weakness" in the OBR's publication system, linked to the software used for its website. This system, deemed more suitable for smaller entities, lacked the robustness required for handling critical market-sensitive data.

While OBR staff believed they had implemented safeguards, two configuration errors on the WordPress publishing platform bypassed these controls. One involved a plug-in that unintentionally bypassed login requirements for accessing documents intended for future publication. The other concerned the directory where the file was stored, allowing direct downloads. The OBR had previously obtained an exemption from using a more secure government publishing platform to maintain its autonomy. The big question: Was this autonomy worth the risk, given the consequences of the leak?

A Treasury spokesperson acknowledged the OBR's report, promising a ministerial response in due course. What are your thoughts on this situation? Was Hughes right to resign, or was he made a scapegoat? Could this incident have been prevented with better security measures, or was it simply an unavoidable human error? And most importantly, how does this affect your trust in the government's economic forecasts? Share your opinions in the comments below!
