Following the four-week trial at Southwark Crown Court, Butt and Asif were each found guilty of conspiracy to accept corrupt payments and conspiracy to cheat, offences that carry a maximum jail term of seven years.
Amir, 19, pleaded guilty to the same offences at a pre-trial hearing two weeks before the case began, a fact not revealed to the jury until they had returned verdicts on his senior colleagues on Tuesday afternoon after more than 17 hours of deliberation.
At the pre-trial hearing Ben Emerson, QC representing Amir, said the player had been subject to “extreme pressure” from senior colleagues: “Amir wants to make it clear he wants to take full responsibility for what he did by deliberately bowling two no balls.
“This vulnerable 18-year-old boy, as he was then, was subjected to extreme pressure from those upon whom he should have been able to rely. He recognised the damage he has caused Pakistan cricket and he wants to do his best to put this right.”
