Letosnik, a seventh dan in the sport, was President of the Czech Judo Federation (CSJ) between 1996 and 2007.

He later became the honorary chairman of the organisation and is said to have dedicated his life to judo as a coach, referee and sports director.

A close friend of International Judo Federation (IJF) President Marius Vizer, Letosnik created and organised a cadet tournament in his home city Jicin.

The event became recognised internationally.

Vladimir Barta, the IJF's head sport director, said: "We are losing one of our judo icons. 

"Many generations will remember Mr. Letosnik and his dedication to promoting judo in the country and outside its boundaries. 

"Some years ago he organised the Jicin Tournament which became one of the strongest and most famous tournaments for cadets, where many future world and Olympic champions, such as Daniel Lascau, Teddy Riner and Lukas Krpalek, participated and won."

Jiri Dolejs, the current President of the CSJ, added: "It is a huge loss for Czech judo. 

"We are really grateful to Mr. Letosnik for all his work and efforts and we bow to mark his memory."

Letosnik's son, Milan, was a member of the Czech national judo team.

Last month's European Judo Championships were held in Czech capital Prague.
