UK Launches Inquiry into Leak of Bank Tax Measures

11:29 AM EST, 11/10/2026 (MT Newswires) -- The UK government is investigating a potential leak of details regarding the bank corporation tax surcharge before Chancellor of the Exchequer John Healey announced the measures in his recent Autumn Budget statement. In a letter to the British parliament's Treasury Committee published Tuesday, Treasury Permanent Secretary James Bowler said he was assured that banks, representatives or trade bodies were not briefed on the details of the bank tax changes before the chancellor delivered his speech. Bowler also noted there was a "necessary widening" of the circle of knowledge within government prior to the speech. Bowler added that the Treasury is cooperating with the UK Financial Conduct Authority regarding the matter. Treasury Committee Chair Meg Hillier said she will push for answers from Healey when he appears before the committee on Wednesday on how market-sensitive information that could affect the share price of banks was circulating before the announcement.
