http://news.bbc.co.uk/sport1/hi/cricket/other_international/pakistan/9395588.stm Former Pakistan wicketkeeper Zulqarnain Haider has vowed to "name and shame" players he believes are engaged in corruption in cricket. Haider, 24, sought asylum in the UK in November after claiming he had received death threats for refusing to help fix two games against South Africa. "There are big names involved in these illegal activities, but they're getting away with it," he told PakPassion.net. "I am ready to name and shame them, if asked by the relevant authorities." Last weekend, three Pakistan players were banned from playing for five years by the International Cricket Council . Salman Butt, Mohammad Asif and Mohammad Amir were accused of spot-fixing in the fourth Test between Pakistan and England at Lord's last August, but have always denied any wrongdoing. All three can appeal against the bans to the Court of Arbitration for Sports, based at Lausanne in Switzerland. Despite the bans, Haider claimed thorough investigations were "not being carried out". He continued: "Players are going to be even more careful now and I know they are watching their backs and attempting to make it even more difficult for the ACSU (the ICC's Anti-corruption & Security Unit) and ICC to catch them out." Haider suggested that one way to keep tabs on players would be to subject them to greater financial scrutiny. "What needs to happen very soon is for an organisation to be set up by the ICC for the specific purpose of looking into the bank accounts and financial dealings of all international cricketers," he said. "This can be an offshoot of the ACSU and should contain individuals who have previously worked in the legal profession or the world of finance. "The new organisation needs to work closely with all of the international cricket boards who should offer their utmost cooperation. "The player contracts with respective boards should have a clause in the contract stating that all financial transactions have to be transparent and details of all bank accounts irrespective of location, have to be revealed by the cricketer to the board and investigating authority." Haider's contract with the Pakistan Cricket Board was terminated following his flight to the UK but he does not regret leaving the national team camp in Dubai. "I gave up everything in cricket," he said. "I had a promising career ahead of me and I sacrificed it all, but I don't have any regrets and my mission now is to clean up the game. "I am prepared to do anything to help in totally cleaning up cricket."
