ADRIAN LEWIS and Keith Deller have announced that they have ended their management partnership.
World number two Lewis has been managed by 1983 World Champion Deller since 2010, claiming two World Championship victories himself at Alexandra Palace during their three-year partnership.

"It has been a successful time for all concerned, and we parted on amicable terms and by mutual agreement, and I'd like to assure my fans that this move does not affect my commitment to the sport - it is just time to move on.
"Keith will continue to manage other players and provide Sports Management services, and I wish him all the best for the future.
"I would like to thank my sponsors for their continued support as I look to carry on the form which I showed in the World Championship into the rest of 2013."
Keith Deller added: "I would like to thank Adrian for the three years we had, and it was a pleasure to act as his Manager.
"It has been an amazing journey, and for Adrian to win two World Championship titles in our three years was a fairytale come true.
"I wish him every future success and we part on the best of terms. I would also like to take this opportunity to thank Adrian's sponsors - Albemarle & Bond, BetVictor, Target Darts and Dulux Decorator Centres - for their great support.
"Keith Deller Sports Management will continue to work with professional darts players to arrange exhibitions, presentations, sponsorships and possible Management."
