Chandler's International Sports Management confirmed the split to the Telegraph, but declined to comment any further. Westwood also declined comment. He has reportedly signed with IMG.
Chandler started ISM in 1989 after 15 years on the European Tour. Westwood was one of his earliest clients and the player and agent were close off the golf course, too. They owned several racehorses together, including one named Hoof It.
The Telegraph reported there is a possible legal dispute between Westwood and ISM.
