When does a tip become cheating?

Horse racing is to be bound by a new set of guidelines to try to fight the problem of inside information.

The BBC has learned the results of a two-year inquiry by the Horseracing Regulatory Authority (HRA), which will be published later this month.

They will include a definition of insider trading, better education for jockeys, tighter rules for the media and greater powers for bookmakers.

The HRA says it is determined to do all it can to make racing honest.

Paul Scotney, the HRA's head of security, told BBC One's Inside Sport programme that racing would probably never be 100% clean, but added: "Over the last 18 months, racing is much cleaner than it was.

"What there wasn't in the past was a perceived threat of being caught - and that's what we need to change.

"People need to see if they do wrong, they're likely to be caught, and if they're caught, they're likely to be substantially punished."

During the two years it has taken to complete the inquiry, 10 jockeys have been banned following investigations by the HRA.

The inquiry will define inside information as first-hand information about a horse's wellbeing or the likelihood of it running or not running, that would be known only to a small group of people and would not be regarded as public information.

And it will outline a series of proposals aimed at giving horse racing a better name.

There will be a greater focus on educating all those in the industry, in particular young jockeys and stable lads, about the dangers of divulging inside information, and outlining, in Scotney's words, "their responsibilities when they have that inside information - what they can and can't do with it".
The media and betting agencies will be encouraged to adopt a tighter code of conduct, including allowing the HRA to seize the phone records of any journalist who appears to be profiting from inside information.
Bookmakers will be asked to be tougher, including being encouraged to void the bets of any client who appears to have inside information.
