As only hours remain for the breathtaking Melbourne Cup race, controversy has hit top jockey Damien Oliver who will be riding Americain which is tipped to take out the race today.

Oliver is being investigated for allegedly making a bet on a race at Moonee Valley in 2010 when riding a horse called Europa Poin.

Racing rules prohibit jockeys betting on their own races or selling race information.

Oliver, a two-time Melbourne Cup winner, said he has been a jockey for 24 years and his record and reputation is honest, committed and trustworthy.

Despite the controversy, Oliver will ride Americain today.

This year’s Melbourne Cup comes 10 years after Oliver won the 2002 Cup on Media Puzzle.

When asked for a comment on today’s $6.2 million race, Oliver said catch me if you can.
