Adam Brickell to leave position as BHA director of integrity, legal and risk.

Adam Brickell will in September leave his position as British Horseracing Authority director of integrity, legal and risk.

Brickell has been with racing's ruling body for seven years but said he wants to move on to a "fresh challenge" following the completion of the BHA's integrity review, which was published in March.

He said: "I have thoroughly enjoyed working for the BHA, but I've come to the conclusion that senior roles in its future structure are unlikely to offer a balance of responsibilities which matches my areas of experience and interest."

The BHA said in a statement that Brickell was "integral" in the formulation of the 'Members' Agreement', which attempted to align the activities of racing's major stakeholders.

BHA chief executive Nick Rust said: "I am sorry he is leaving, but I fully understand and respect his decision.

"The work Adam led on the integrity review, which we published in March this year, identified several themes which led me to new thinking about how we organise the BHA's core regulatory functions.

"In discussing this with Adam, it became clear that future roles are unlikely to fit with his personal ambitions.

"I was, however, delighted that Adam agreed to stay on until mid-September, as this has enabled him to progress his work on the integrity review and support myself and the board in finalising our new organisational structure."
