Britain’s fiscal watchdog is to publish a detailed breakdown of the £22bn “black hole” that Labour says it inherited after Rachel Reeves presents the budget on Wednesday.

The Office for Budget Responsibility will release the conclusion of its review of how the forecast for departmental spending for its last economic and fiscal outlook, published for the March budget, was prepared.
