Champion jockey Oisin Murphy has vowed to do "everything that I can" to prove his innocence after testing positive for metabolites of cocaine at a meeting in France earlier in the year.

The Kerry 25-year-old was tested by France Galop at Chantilly on July 19, where he partnered The Lir Jet to finish second in the Group Two Prix Robert Papin.
