The Jockey Club yesterday told trainers and jockeys that "only those with something to hide" need fear new measures designed to stamp out corruption in racing.

The Jockeys Association of Great Britain and National Trainers Federation have blasted the revised rules and codes of conduct aimed at licensed professionals - primarily trainers and jockeys - published yesterday in the Jockey Club's Integrity Review Report.

It also announced a range of criteria designed to increase deterrents to malpractice in racing and so further strengthen public confidence in the integrity of the sport. The measures aim to deter licensed persons passing on information that is not in the public domain for reward, to limit association between jockeys and trainers with bookmaking organisations and to set out codes of conduct on co-operation with investigations and reporting of malpractice and unusual financial transactions. They will take effect from January 1st.
