The UK government has launched an investigation into the leak of bank tax details ahead of the Budget, according to First Squawk. The disclosure concerns tax measures affecting UK banks that were revealed before the official fiscal announcement. The probe underscores scrutiny of Budget confidentiality and how early signals on bank taxation reach markets. Details of the leaked measures and their fiscal cost have not yet been confirmed. Watch for the government's findings and whether the leak alters expectations for bank levies in the Budget.
