text: Ruby Walsh appears to jump his horse over a moving car in the latest promotional advert for betting firm Paddy Power. The 22-second clip shows the two-time Grand National winner galloping towards the speeding silver car and apparently jumping it as the bookmaker gears up for Saturday's big race at Aintree. Irish jockey Walsh, who is riding Ballycasey in the race, starts the clip by saying: 'This is how I've been getting ready for this year's Grand National.' The clip starts with champion jockey Ruby Walsh describing how he will prepare for the Grand National . The two-time National jockey appears to then leap over the speeding car on his horse . The horse clears the car, which Paddy Power say was travelling at 40mph, and lands . Walsh celebrates with a raised arm after completing the 'stunt' Paddy Power claims he jumped straight over the car, which was said to be travelling at 40mph. The horse barely clears the car's roof before landing. Walsh stands upright and raises his right arm in apparent celebration after the horse lands and gallops away. It is not the first time the bookmaker has produced a controversial advert ahead of a major racing festival. In February 2012, a publicity stunt prior to the Cheltenham Festival featured a suited hitman firing tranquillizer darts at unsuspecting members of the public, promising to 'take care of the chavs - veterinary style.' It was inspired by loutish racegoers fighting at Ascot. Another advert released ahead of the 2012 Cheltenham Festival showed a clip of transgender racegoers and invited viewers to spot the 'stallions' from the 'mares.' Walsh pictured after riding Sempre Medici to victory on Irish Grand National Day at Fairyhouse last week . The Irish jockey will ride Ballycasey in Saturday's Grand National at Aintree . It was banned from television broadcast by the Advertising Standards Authority (ASA) after it received 92 complaints the ad was offensive and condoned and encouraged harmful discriminatory behaviour. Although banned from TV, both adverts remain easily accessible on the internet. Another advert ahead of the Ryder Cup last year saw UKIP leader Nigel Farage feature in a spoof political broadcast in which he was 'swinging for Europe'. Walsh, 35, has twice won the Grand National before - on Papillon in 2000 and Hedgehunter in 2005.
