Pakistan cricket was thrown into turmoil on Wednesday with the country's Board putting a lifetime ban on former captains Mohd Yousuf and Younus Khan because of their bad influence on the national team. The Pakistan Cricket Board (PCB) also imposed a one-year ban on Shoaib Malik and Rana Naved-ul-Hasan in the wake of the team's disastrous tour of Australia and fined 2 million rupees each. In a statement PCB said that an inquiry committee headed by Wasim Bari has been formed to probe the reasons for the debacle in Australia. The Akmal brothers — Kamran and Umar — and Afridi have been put on probation for six months besides being fined between 2-3 million rupees for indiscipline on the tour. The punishments are set to impact the composition of Pakistan's World Twenty20 Championship. The team is the defending champion in this format and the 15-man squad for the event is due to be out by the end of this month.
