Mistry reached a high of eighth in the world in singles

Mistry has been the undisputed British number one for more than 15 years, during which time he has won 13 National singles titles.

"This was one of the most difficult decisions of my life," he said.

"But I could not continue to play if I could not perform to my highest standards and expectations."

He added: "I have had a most wonderful 20 years and I thank everyone who has helped and supported me to reach levels of performance that I never dreamed were possible when I took up the sport at the age of 19.

"I will miss tennis enormously but look forward to putting something back into the game that I love so much. I wish all my colleagues in GB the very best of luck in the future."

Mistry, who competed in four Paralympics, has been ranked in the top 10 in the ITF Wheelchair Tennis World rankings in either singles or doubles since 1995.

His highest singles ranking was eighth in August 2000 and his highest doubles ranking was second in May 2002.

Mistry has won 67 international career titles - 20 singles and 47 doubles titles on the NEC Wheelchair Tennis Tour.

One of his career highlights came in 2005 when he partnered Frenchman Michael Jeremiasz to victory in the inaugural Wimbledon men's wheelchair doubles competition.
