If, on Wednesday morning, you’d asked me how this entire Budget process could ever get more chaotic and absurd I might have said “I suppose the entire thing could leak, before the Chancellor delivers it.” Then again, I probably wouldn’t have suggested such an implausible scenario.

But at 11.44am yesterday morning, just ten minutes before PMQs and 45 minutes before Rachel Reeves was due to stand up in the Commons, the unthinkable happened.

The OBR’s full assessment of the entire Budget, including its costings, forecasts and analysis, was accidentally published.
