Britain’s Office for Budget Responsibility has shifted from an approach of trust towards the finance ministry to one of “trust but verify” after inaccurate spending forecasts provided before March’s budget statement under the last Conservative government.
Last week, the OBR said the Treasury had failed to share information about large upward pressures on day-to-day spending and unusually high spending from emergency reserves.
“The way I would characterise it is that we are moving from a system of trust to a system of ‘trust but verify’,” OBR Chair Richard Hughes told the House of Commons’ Treasury Committee on Tuesday.
“We want to … make sure that we’re satisfied that what happened, the failure of oversight that very clearly happened in March, doesn’t happen again.”
New Labour finance minister Rachel Reeves said the previous government, which oversaw the last budget, had left a 22 billion pound ($29 billion) black hole, requiring her to raise taxes by much more than she had planned before July’s election.
The Conservatives say most of this hole reflects Labour’s choices on public-sector pay or temporary overspending that is routinely recouped in a normal financial year.
However, the OBR said that if finance ministry officials had been more open in the run-up to the March budget – as they had been in the past – it would have forecast materially higher spending for the current financial year.
“There were about 9.5 billion pounds worth of net pressures on departments’ budgets which they did not disclose to us as part of our usual budget preparation process … which under the law … they should have done,” Hughes said.
From now on the OBR will ask for a more detailed breakdown of the finance ministry’s spending forecasts, he said.
Lawmakers would need to ask the finance ministry at a hearing on Wednesday why it had failed to provide the necessary information, Hughes said. “There may have been a misunderstanding of how the law ought to be interpreted.”
A Treasury spokesperson said that at the time of the spring budget they “communicated to the OBR the decision that ministers would manage spending pressures by making offsetting savings”.
“This was within the law,” the spokesperson said, adding that they had accepted all recommendations put forward by the OBR in its review of the March 2024 forecast.
The OBR said it did not consult former finance minister Jeremy Hunt, who oversaw March’s budget, as the review looked into the actions of officials, not ministers.
