Salman Butt, the Pakistan captain who is believed to have led the plot at a Test match against England last year, was jailed for 30 months.

Mohammed Asif, who bowled one of three pre-agreed no-balls as part of the scam, was handed a year’s jail sentence. Mohammed Amir was given a six-month sentence.

All three must serve their time in English prisons.

The scam, which saw the gang paid £150,000 to deliver three no-balls at a precise time during the Test, also involved player agent Mazhar Majeed.

The agent was handed a 32-month sentence after Mr Justice Cook said he was equal to Butt as one of two “architects of the fixing”.

The judge is understood to have softened what would have been a four-year sentence for Majeed in recognition of his guilty plea.

Amir was also given a lenient sentence for a guilty plea, which the 19-year-old will serve in a young offenders’ institution.

Butt, an extremely promising player, has been banned from all forms of cricket for five years.

The judge said: “That is the punishment imposed by the cricket authorities, but these crimes of which you have been convicted require that a sentence be imposed which marks them for what they are and acts as a deterrent for any future cricketers who may be tempted.”

Although the bowling of no-balls only leads to a team conceding one run, the judge insisted that the case’s seriousness comes from the damage it has done to the credibility of the sport.

“Now, whenever people look back on a surprising event in a game or a surprising result or whenever in the future there are surprising events or results, followers of the game who have paid good money to watch it live or to watch it on TV will be led to wonder whether there has been a fix and whether what they have been watching is a genuine contest between bat and ball,” the judge said. “What ought to be honest sporting competition may not be such at all.”
