Pakistan fast bowler Mohammad Asif highlighted the involvement of his former skipper Salman Butt while in the witness stand during day 13 of the alleged spot-fixing trial by telling a London court "the captain knows".

The former investigations editor at Rupert Murdoch's News of the World tabloid denied on Wednesday that his story allegedly exposing spot-fixing in Pakistan cricket was the result of phone hacking.

Pakistan cricketers were ready to throw one-day internationals and Twenty20s in a bid to undermine then-captain Shahid Afridi and make "a hell of a lot of money", a London court heard on Tuesday.

The cricket world has been hit by allegations of nexus between players and bookies but the two Indian players - Harbhajan Singh and Yuvraj Singh - who were mentioned in the reports as also Cricket Australia rubbished suggestions of any wrongdoing.

Mazhar Majeed, the agent of several Pakistan players, was offered US$1 million by an Indian bookmaker to ensure the team lost the third Test at The Oval against England, which they eventually won, a court heard in London on Tuesday.

Pakistan were to throw at least one limited-over international on the 2010 tour of England, a court was told on Monday, and only the timing of the News of the World's expose seemed to prevent such a result from occurring.

The agent at the centre of the spot-fixing allegations tried to impress an undercover journalist, posing as an Indian businessman, with a series of boasts.

Mazhar Mahmood, the journalist who conceived the plan that resulted in spot-fixing allegations against Pakistan cricketers Salman Butt and Mohammad Asif, will be appearing in front of the jury at Southwark Crown Court on the fourth day of the trial on Monday.
