LAHORE - Pakistan cricket chief Ijaz Butt has officially requested a review over fast-rising paceman M Aamir's five-year ban on charges of corruption, a spokesman of PCB revealed on Saturday. Te request to the International Cricket Council (ICC) was made later Friday. "As the Anti-corruption tribunal has asked for a review on the code of conduct, we too, have requested the ICC to have a review on the five-year ban on Aamir," Butt said. Aamir, Salman Butt and Asif were banned on charges of corruption during the Lord's Test against England last year. Salman was banned for 10 years, with five years suspended, and Asif for seven years, including a two-year suspended ban. The anti-corruption tribunal, headed by Michael Beloff, while announcing the verdict last week also requested the ICC to review the minimum sanction in their code of conduct, which is five years, in special cases. It was widely speculated that Aamir, aged only 18 and having never violated the ICC code of conduct in his two-year international career, would get a two or one-year ban, but the tribunal had to impose five years, the minimum for this type of breach. Butt admitted the chances of the ban being reviewed or reduced were remote. "There is one out of million chance as the final decision would rest with the ICC," said Butt. Butt hoped the request for a review. Butt also spoke in detail on the spot-fixing scandal, blaming the three banned players -- Salman Butt, Aamir and Asif - for letting the country, the board and their team down. People blamed the PCB for not doing anything for the players when the spot-fixing allegations first broke out against them in August last year on the tour to England, but the chairman of the Board clarified that it did everything it could for the trio. "The truth is that when Scotland Yard started its investigations we gave the players full support including legal help and the Pakistan High Commission also got involved but they were not honest with us and misled us by denying everything. "Later we found out that one of the players had made 140 calls and sent SMS-es, while another sent 120 SMS-es and calls after the incident first took place. They let us down and disappointed everyone a lot." "The anti-corruption tribunal said that the ICC needed to review its existing anti-corruption code of conduct laws and this will be discussed at the three-day executive board meeting of the ICC in Dubai from February 14," Butt said. Butt said he hoped that Pakistani players will learn a lesson from the bans imposed on the trio and this will serve as a deterrent to them. "The message is loud and clear that there is nothing to be achieved by getting involved in these things. We had lined up contracts worth millions for Aamir and he had a great career ahead of him but he wasted it all because of his greed."
