The Aga Khan has severed his relationship with retained jockey Christophe Soumillon after the rider was criticised for comments he made about trainer Andre Fabre at a charity event.
Soumillon will ride for the Aga for the remainder of the current Flat season, but then their successful association will come to an end, according to the the Racing Post
The Belgian pilot was on board the brilliant Zarkava last season when she romped to a sensational Arc victory.
The paper claims the 28-year-old Soumillon made the comments about Fabre during a jockeys' gala dinner at the Deauville Casino on Saturday.
He said he was happy that Alain de Royer-Dupre had become champion trainer, and added of Fabre: "He's so small you can hardly see him."
Soumillon later apologised.
A statement from the Aga Khan said Soumillion's contract will not be renewed for 2010 because "human relations have become difficult".
The possibility of Soumillon riding for the Aga again one day hasn't been ruled out.
