And so the cycle continues. "We cannot continue to accept this doom-loop of dead-end investigations in which everybody in the Treasury throws their hands up in despair, but nobody is ever found to have done anything wrong.”Dame Meg HillierPA MediaShe added: "The Treasury still has questions to answer on how market sensitive information which was likely to affect the share price of banks was circulating around newsrooms before it was given to Parliament. “I will be pushing for those answers when the Chancellor appears in front of the Committee tomorrow (Wednesday) afternoon.”The inquiry was expected to focus on a Bloomberg report published at 10.45am on the day of the Budget, which said Mr Healey's increase in bank taxes would be less severe than lenders had feared and would be temporary.Read MoreWhen the Chancellor delivered his Budget later that day, he confirmed that the bank corporation tax surcharge would be temporarily increased from three per cent to six per cent for 15 months from January 2027 to help fund measures aimed at easing cost-of-living pressures.The Budget bank tax was lower than feared in the CityAFP/GettyShe also raised concerns that bank share prices seemed to react to the report before the Budget was formally presented to Parliament, highlighting the potential market sensitivity of the information.The committee has also urged the City watchdog, the Financial Conduct Authority, to probe the apparent early release of details of the bank tax.
