Fed up of being accused of doping, Rafael Nadal has written to the president of the International Tennis Federation and asked for all of his drug-test results and blood profile records to be made public.

In a letter obtained by The Associated Press, the 14-time grand slam champion says "it can't be free anymore in our tennis world to speak and to accuse without evidence."

Nadal's letter was sent to ITF President David Haggerty on Monday, the same day he filed suit against a former French government minister who had suggested he had been doping.

He asked for his complete history of anti-doping controls and tests to be made public and for all his future test results to be released.
