Melbourne Cup winner Michelle Payne stood down after testing positive to 'banned substance'
Racing Victoria Stewards have announced they will conduct an inquiry into the results of a urine sample by Melbourne Cup winning jockey Michelle Payne, which has tested positive for a banned substance.
The sample was taken at the Swan Hill Cup meeting on 11 June 2017.
Stewards received a report from Racing Analytical Services Limited (RASL) confirming the presence of Phentermine, an appetite suppressant which is banned under Australian Rule of Racing 81B.
Ms Payne, 31, was advised of the findings and has been stood down from riding in races and trackwork by Stewards from 23 June 2017.
She has been requested to attend the inquiry which will be conducted on Thursday morning at Racing Victoria offices in Flemington.
There were fears for Payne's career after she suffered a torn pancreas in a fall last year, but she returned to the track and finished fifth on the Australian-owned Kaspersky at the Group One Queen Anne Stakes at Royal Ascot last week.
Payne, from a family steeped in racing, made international headlines when she became the first woman to win Australia's 155-year-old Melbourne Cup on Prince of Penzance at Flemington in 2015.
