Bookies were licking their wounds at the Cheltenham Festival on Wednesday after a series of big bets were landed.
Renowned gambler and Brighton and Hove Albion football club chairman Tony Bloom said he had "a few quid" on his horse Energumene, who won the Champion Chase for the second year in a row.
But betting firm Star Sports, who Bloom often backs with, reported they took a £400,000 (€456,000) to win £580,000 (€662,000) bet on 6/5 favourite, who is trained by Willie Mullins and was ridden to victory by Paul Townend.
