London: Britain's Andy Murray and coach Ivan Lendl have mutually agreed to end their two-year partnership, the Wimbledon champion announced Wednesday.
Under the guidance of the 54-year-old Czech, 26-year-old Murray won the Olympic gold in 2012, and then the US Open, his maiden Grand Slam title, and also lifted the Wimbledon trophy in 2013, becoming the first British player to triumph at the venue in 77 years -- since Fred Perry in 1936.
In a joint statement on Murray's website, it appeared Czech-born Lendl, himself a multiple Grand Slam champion, had been the instigator of the split.

"Working with Andy over the last two years has been a fantastic experience. He is a first-class guy," said Lendl.
"Having helped him achieve his goal of winning major titles, I feel like it is time for me to concentrate on some of my own projects moving forward including playing more events around the world which I am really enjoying.
"I will always be in Andy's corner and wish him nothing but great success as he too goes into a new phase of his career."
Lendl has recently played exhibitions in Kansas City, Oklahoma City, Nashville, Charlotte and at Earl's Court in London. Lendl has also been giving clinics in the Canary Islands as well as opening new courts in South Carolina at the Ivan Lendl Junior Tennis Academy.
Murray, who is returning from back surgery, added: "I'm eternally grateful to Ivan for all his hard work over the past two years, the most successful of my career so far.
"I'll take some time with the team to consider the next steps and how we progress from here," added Murray, who continues his return from back surgery and is preparing to defend his Miami title.
Murray was already one of the most talented players of his generation but it was only when working with Lendl, who like the Scot lost his initial Grand Slam finals, that he became a major winner.
Their first significant joint triumph was at the London Olympics before Murray, with eight-time major winner Lendl in his corner, won the US Open -- his first Grand Slam title.
But even that success was topped by Murray's victory over Novak Djokovic in last year's Wimbledon final, a win that saw him become the first British player since Fred Perry 77 years earlier to win the men's singles title.
Murray, 26, was first introduced to tennis by his mother, Judy, now the captain of the British women's Federation Cup team.
But as a professional tennis player he worked with several coaches including compatriots Mark Petchey and Miles Maclagan, as well as Spain's Alex Corretja and American Brad Gilbert before joining forces with Lendl in December 2011.
Although Lendl had no track record as a tennis coach, he was widely regarded as the man capable of turning Murray into a champion given he too had lost his first four Grand Slam finals.
Murray, speaking after his Wimbledon triumph, said of Lendl: He's made me learn more from the losses than I did before and he's always been very honest with me and believed in me when other people maybe didn't.
"Ivan's been very patient, as I'm not always easy to deal with. He's also honest with me.
"If I work hard he's happy, if I don't he's disappointed and he'll tell me. He has got me mentally slightly different going into these big matches."
Although Murray's form has dipped since his Wimbledon victory, most observers attribute the downturn to his back injury and subsequent surgery.
