Nina Gunning For Victory In National Nina Carberry is set to take on brother Paul in the first ever brother/sister clash in the Grand National - but William Hill can´t split the talented siblings and offer 5-6 each about who will get furthest in the race*. Nina has been handed the ride on 40-1 shot Forest Gunner, who sparked a massive gamble last year when ridden by Carrie Ford and came close to costing the bookies millions of pounds when finishing fifth. Paul, who has already tasted National victory aboard Bobbyjo in 1999, is booked for Sir OJ who is priced at 33-1. Hills spokeswoman Jennie Prest said, 'While Forest Gunner doesn´t have the form he had going in to last years race he is still a several times course winner and Nina is the most accomplished female jockey of the times. We are definitely in fear of the ´female flutter´ factor that means Nina is sure to be a strong housewives choice and any gamble would cost the industry millions if she were the first female jockey ever to win the race.' Hills offer 10-1 for Nina and Forest Gunner to better Carrie Fords fifth place last year (so far the best position ever acheived by a female jockey) and also 8-11 for the pair to complete the National course and Even money that they don´t get round.
