William Hill has reported a record weekly loss in January after a series of "customer-friendly" football results.
The betting firm said it lost £14 million in the third week of January as a number of key Premier League fixtures were won by the favourite team.
William Hill said it has not yet made up the losses, reporting a profit of £16m for the first three months of the year, down 19% - it was also hit with £20m costs through the new "point of consumption" tax and higher taxes on machines.
Bets placed at the horse racing's Cheltenham Festival was up 29% and mobile betting for the period grew by 48%.
James Henderson, chief executive of William Hill, said: "Operating profit benefited from the changes we made to the staffing model in April 2014 as well as from the reduction in costs driven by shop closures".
