JPMorgan Chase CEO Jamie Dimon met with UK Prime Minister Andy Burnham and Chancellor of the Exchequer John Healey at Downing Street on Wednesday, warning them against increasing the tax burden on banks in next month's budget. The UK government is scheduled to announce its fiscal budget on October 28, which may include policy adjustments such as a windfall tax on banks and oil companies. Dimon had previously stated publicly that JPMorgan Chase might reconsider its new building project in London's Canary Wharf if the new government were "hostile" towards banks.
