Three of Pakistan's star cricket players are defending themselves at an anti-corruption hearing in Doha.
Former Pakistan test captain Salman Butt and his two opening bowlers, Mohammad Amir and Mohammad Asif, were suspended by the International Cricket Council (ICC) in September following allegations of spot-fixing.
They were accused of bowling deliberate no-balls in August's fourth Test against England at Lord's.
All three players have denied any involvement in the illegal practice.
The trio could face life bans if found guilty of breaking the ICC's code of conduct, the BBC reports.
The men were provisionally suspended and charged by the ICC, and were also questioned by Scotland Yard detectives in London about the allegations.
The tribunal began on Thursday and is scheduled to last no longer than six days.
