There’s no need to shout marb 
This is an interesting quote by Scotney —
Scotney was clear on one rider, who is being closely investigated by his department. "We’ve got one cheat still out there who is still in our sights, and we are quite confident that we will get him. He’s been cheating for years, but he’s involved in two investigations at the moment, and his time will come," he added.
If they know he has been cheating for years then why have they not nailed him yet? Also how long will it be until Betfair open a market to bet on who this jockey is
I know who would be favorite but I had better keep quiet.
