A charity set up by the billionaire boss of Bet365, Denise Coates, may have saved her online gambling empire more in tax than the foundation has yet given to good causes, Guardian analysis suggests.

The Coates family are among Britain’s biggest taxpayers, and contributed an estimated £376m [$493m] to the exchequer in 2023 via business and personal taxes. That includes Bet365’s corporation tax bill and levies on Denise Coates’ record-breaking wages and dividends.
