Betfair have confirmed that they have voided all bets placed on the 2pm race at Leopardstown this afternoon.
The online gambling company had been facing a £23m payout following a mistake on their website which allowed customers to bet on Voler La Vedette at a price of 28-1.
The seven-year-old, which should have started with odds of 2-1, went on to win the Christmas Hurdle ahead of Mourad.
Following the result, Betfair suspended the market in order to investigate the incident.
"Customers betting in-play on this race will have seen that Voler La Vedette was available to back at 29 when the in-running market was suspended, and that a considerable sum was matched on the clear winner at that price," read a Betfair statement. "An investigation has revealed that this was due to an obvious technical fault which allowed a customer to exceed their exposure limit.
"In accordance with our terms and conditions, all in running bets on this race, both win and place, will be made void."
Betfair also apologised to those who had backed Voler.
