Tom Tate has announced he has severed his connection with owners Jim and Fitri Hay.
The Tadcaster trainer has had an association stretching back six years with the couple, who are largely based in Dubai.
Major successes together in the pink and green silks came in last year's Gordon Richards Stakes at Sandown with Kings Gambit and the 2010 Winter Hill Stakes with Distant Memories, both of whom placed in other Group races.
Tate said in a statement to Press Association Sport: "I have enjoyed some special moments training for Jim and Fitri over the last few years with good horses such as Distant Memories, Kings Gambit and Balcarce Nov.
"They have moved on with a concentration on horses with Coolmore and some up-and-coming young trainers in Southern-based training establishments, near where they now live.
"I just want to say that I am very much still open for business, especially for local owners who perhaps have felt that there was no room for them here before."
