In an interview, Butt also said the International Cricket Council's handling of the investigation was “terrible” and its chief executive, Haroon Lorgat, should be fired.

The ICC opened another investigation over the weekend into alleged Pakistani fixing on the tour with England, following claims that the scoring pattern in Pakistan's innings in last Friday's one-day match was prearranged.

Earlier, the ICC suspended three players over allegations they were paid to deliberately bowl no-balls during the fourth test against England.

Butt said the ECB had sent a letter to the ICC, which he claimed suggested that the allegations of match fixing pertained solely to Pakistan. He did not provide a copy of the letter or say when it had been sent.

“This is biased thinking. This is biased views. This is biased action taken by some of the people,” Butt said, his voice rising with anger. “We have started an in-house investigation and we will book everybody who has done this.

They said they will sue me. I will sue them. This is something totally wrong.” Butt also accused the ICC of suspending players Salman Butt, Mohammad Asif and Mohammad Amir without proof.

The trio were suspended under the ICC's anti-corruption code following allegations by the British tabloid News of the World that they were paid to deliberately bowl no-balls at prearranged moments in the fourth test at Lord's.

London police on Friday passed their initial evidence to prosecutors to consider charges.

“How have they have come to this conclusion?” Butt said of the suspension. “There has been no investigation. This is not fair. This is definitely a conspiracy against Pakistan cricket.” Butt went on to suggest that the motives behind the suspension may be to undermine Pakistan's chances in next year's World Cup.

“Half our team is destroyed,” he said. “We are preparing for the World Cup. Maybe there are some countries that don't want us to play in the World Cup. This is wrong.

We will look into the conspiracy and definitely, definitely, definitely take action.”
