Burnham’s Budget must not be overshadowed by the OBR

By the Editorial Team · Tuesday, October 6, 2026

Chancellor John Healey will present the first Budget of Prime Minister Andy Burnham’s government on October 28, marking a key test of their economic strategy 100 days into office. The Budget’s significance lies in how the administration navigates the influential forecasts of the Office for Budget Responsibility to balance fiscal discipline with priorities like cost-of-living relief amid geopolitical and economic pressures.

On October 28, Chancellor John Healey is set to deliver the first Budget under Prime Minister Andy Burnham’s administration, marking a significant early test for the new government. This Budget, arriving exactly 100 days after the government’s formation, is expected not only to signal economic priorities but also to navigate the complex relationship with the Office for Budget Responsibility (OBR), which has become a key player in Britain’s fiscal landscape.

The OBR, established in 2010 as an independent body for auditing the government’s economic forecasts and fiscal policies, has grown in prominence over the past decade. Its assessments — covering growth projections, inflation rates, borrowing costs, and policy costings — now heavily influence public and political discourse around the Budget. The institution’s enhanced role was underscored by the fallout from the former prime minister Liz Truss’s 2022 “mini” Budget, which famously bypassed the OBR and led to market turbulence. Subsequent reforms have cemented the OBR’s involvement, requiring future governments to integrate its analysis into fiscal planning.

For the Burnham government, the OBR’s forecasts will pose both a challenge and an opportunity. While the Treasury’s traditional “red book” Budget document carries historical and procedural significance, it is the OBR’s “blue book” economic report that commands greater attention from policymakers, journalists, and analysts alike. Officials devote extensive time in advance of the Budget to detailed cabinet deliberations and spending negotiations, but the public and media focus often centers on the independent evaluation of the numbers presented by the OBR.

Inside government circles, there is an understanding that simply accepting the OBR’s projections could leave ministers politically constrained. Analysts suggest that ministers should actively frame the OBR’s figures to support the government's narrative. For instance, if geopolitical events such as the conflict involving Iran have pushed inflation forecasts higher, those economic pressures can be cited to justify prioritizing cost-of-living relief. Conversely, should inflation projections improve, the government may argue for more ambitious fiscal measures. Rising borrowing costs have also been linked to the prime minister’s stated goal of protecting household finances by maintaining manageable mortgage rates, aligning fiscal discipline with public messaging.

The upcoming Budget will thus be a barometer of the Burnham administration’s ability to balance economic realities with political communication. While the OBR’s impartial authority remains substantial, the government’s response to its forecasts will demonstrate how it manages fiscal challenges amid external pressures and domestic expectations. The first Budget under Burnham offers a crucial moment to define the government’s economic direction and its capacity to shape the narrative beyond the numbers themselves.
