Mullins loses Be My Royal appeal
The horse was originally disqualified by the Jockey Club's disciplinary panel at a two-day hearing in January after the horse failed a post-race drugs test for morphine.
A contaminated food supply was found to be the source of the drug and although Mullins was not fined, he was ordered to pay £5,000 in legal costs and Be My Royal was stripped of his victory in the Newbury race.
