Australia and Pakistan shared the one-day series title in Nairobi

A newspaper in Pakistan claimed to have seen a letter from Lord Condon, head of the ICC Anti Corruption and Security Unit to the Pakistan Cricket Board.

In the letter, Condon alleges Waqar Younis' team under-performed in one-day tournaments in Morocco and Kenya.

"It is not appropriate for the ICC to make a comment one way or the other," said ICC boss Malcolm Speed.

The newspaper quotes Lord Condon as saying in the letter: "None of [these] allegations ... are capable of proof, at this stage.

He told the PCB: "A worrying amount of information is being received from different sources in different countries and I place it before you in case it resonates with your own information and anxieties about recent results."

Speed emphasised the ICC's commitment to "ensuring that the game is never again tainted by corruption.

"Through the Anti Corruption and Security Unit it now has in place a professional security and investigative team with the resources to deal with this threat," he added.

In August 2002, Pakistan won just one of four matches in a three-team series won by Sri Lanka in Morocco.

They subsequently lost to Australia twice in Nairobi, reaching the final after beating Kenya twice, but the spoils were shared with Ricky Ponting's side after a rain-hit final.

Their poor results led to the sacking of coach Mudassar Nazar.
