Bookmaker Paddy Power has today announced that it will refund all losing single bets placed on tomorrow's Martell Grand National if Bobbyjo wins the race.
The offer applies to all single win bets through its telephone betting service or through any of its 118 shops in the Republic.
The firm's managing director Stewart Kenny said today: "I have no doubt in my mind that if Bobbyjo wins on Saturday there will be queues longer than the January sales outside our shops but it's all in good spirit."
Bobbyjo became the first Irish-trained horse to win the National for 24 years when successful last season and will bid to become the first horse since Red Rum in 1974 to win the race back-to-back.
