Chancellor Rachel Reeves is backing an inquiry into pre-Budget leaks from the Treasury which knocked business and consumer confidence and moved markets.
The chief secretary to the Treasury told the Commons on Wednesday an inquiry into pre-Budget leaks was under way, led by top Treasury civil servant James Bowler and had "the full support of the chancellor".
Policies such as a freezing of income tax thresholds, a pay-per-mile levy on electric vehicles and a tourist tax were all reported in the lead-up to the Budget on 26 November.
A downgrade of UK productivity from the Office for Budget Responsibility, and a plan to raise income tax rates, later abandoned, were also briefed to media.
