Update Monday morning - Racing Victoria (RV) on Monday announced that Jamie Stier, currently Chief Regulatory Officer at the British Horseracing Authority (BHA), has been appointed to the role of Executive General Manager, Integrity Services.
Earlier report - The BHA announced on Sunday afternoon that one of its top officials is leaving to return home to Australia next year.
Jamie Stier, chief regulatory officer, has decided to leave his position and, like his fellow Australian Paul Bittar, the former BHA chief executive will be returning to racing in his homeland.
A departure date has not yet been finalised but Stier will leave during the first half of 2018 and the BHA will be looking for his replacement in the new year.
Stier said: "I have greatly enjoyed the privilege of working in British racing, and more particularly the BHA, during the last eight years.
"I will leave comfortable in the knowledge that the BHA is committed to consistently looking at ways in which the sport can be most effectively regulated to safeguard the reputation of racing and all those involved in it, including the real stars of the show, the horses.
"I have been fortunate to have worked with many fantastic people during my time here, and the current team guiding the BHA is no exception. I would like to thank those who have offered me support during my time here."
Nick Rust, the BHA chief executive who succeeded Bittar, said: "Jamie has made a significant contribution as chief regulatory officer, and in his previous roles at the BHA since he joined in 2010.
"I would like to thank him for his work and wish him well for the future. Our system of regulation has been improving and becoming much more transparent and progressive over the last few years."
Stier is responsible for managing the BHA’s raceday operations, including stewarding, integrity and equine welfare staff.
He also has responsibility for managing the teams that license trainers, jockeys and racecourses, lead the anti-doping and anti-corruption investigations, and running the sport’s equine-welfare programme.
