EQUESTRIAN Australia's high performance manager Brett Mace has resigned.
EA confirmed his resignation today.
It is understood he resigned last Friday.
In a statement to Weekly Times Now, EA said: "(EA) can confirm that Brett has resigned from his position as high performance manager.''
Over the past seven years at EA Mace has overseen dressage, eventing and showjumping teams at two Olympic Games and two World Equestrian Games.
There are a number of reviews being conducted examining the recent selection of the 2012 London Olympic Games equestrian team, including selection procedures, poor performances and expenditure.
Findings of an Australian Sports Commission enquiry conducted in October are yet to be released.
This was specifically charged to investigate the selection nomination for the 2012 London Olympic Games.
There have been many rumours regarding the critical analysis conducted by the new EA board, which is speculated could have far reaching ramifications to athletes in all equestrian disciplines.
There has been speculation in the industry for the reason behind his resignation, however, the EA would not comment on the reason for Maces sudden departure.
