"In our fight against match-fixing we have got to a stage that our Anti-Corruption Unit (ACU) chief Lord Paul Condon can say to us that he believed that the problem of match-fixing is under control but it's not gone for ever," said Speed.

"If we go back to 2000, cricket had a very serious problem with corruption when we saw then a number of captains and other players were implicated. We had to deal with that problem," Speed, an Australian, told reporters after an international seminar on cricket.

"We know that allegations come up and we are vigilant."

The ICC was forced to form the unit after late South African captain Hansie Cronje confessed to taking money from bookmakers in June 2000.

Former Indian captain Moha-mmad Azharuddin and ex-Pakistani skipper Salim Malik were also banned for life after inquires in their respective countries.

"ICC spends in excess of one million pounds on anti-corruption and security unit and we will continue to do that because we believe that it is one of the most serious problems that has confronted cricket," said Speed.

Pakistan banned for life Malik and pacer Ataur Rehman and imposed fines on Wasim Akram, Waqar Younis, current captain Inzamamul Haq, Saeed Anwar, Mushtaq Ahmed and Akram Raza after an inquiry by Justice Malik Mohammad Qayyum in 1998-1999.

A second inquiry conducted by Justice Karamat Bhandari in 1999-2000 into two match-fixing allegations in the 1999 World Cup held in England cleared all players.

Speed expressed satisfaction with both the inquiries.

Meanwhile, Malaysia has postponed a three-match one-day cricket series between former world champions Pakistan and Sri Lanka and hopes to reschedule it in early November this year, officials said Monday.

"After consultation with Pakistan and Sri Lankan officials, the Malaysian Challenge Cup has been postponed but we hope to reschedule it in early November this year," said Malaysian Cricket Association (MCA) president Tunku Imran.

Imran met Pakistani and Sri Lankan officials on the sidelines of the international seminar organised by the Asian Cricket Council.

The series, scheduled for May 25, 27 and 29, was postponed after the MCA failed to get the title sponsorship for the event.

"We wanted to host the event for the development of the game in Malaysia but without the title sponsorship it was unwise to stage such an event," said Imran.

He said he hoped that the ICC, the ACC and other top playing countries would help promote the game in Malaysia.
