A former horse trainer found guilty of race-fixing in relation to the 2013 Tamworth Cup has admitted to similar corrupt conduct in harness racing.
Robert James Clement, 51, was due to face a sentence hearing on Thursday in Sydney's District Court after a Tamworth jury found him guilty of engaging in conduct to corrupt the betting outcome of the Cup.
His co-accused, horse trainer, Cody Glenn Morgan, 30, was found guilty of the same charge and two other offences.
The Crown argued the pair had an agreement to obtain a financial windfall and drenched the winner Prussian Secret just hours before the race.
On Thursday, Acting Judge Colin Charteris was told Clement had previously pleaded guilty to two counts of illegally possessing a firearm.
Before the judge, he then pleaded guilty to facilitating corrupt conduct in relation to a Tamworth harness race and asked the court to take into account two similar matters.
His case was adjourned to September 13.
Morgan is due to give evidence on Thursday afternoon in relation to his sentencing.
