Former Pakistan cricketers Salman Butt and Mohammed Amir will begin their appeals against their jail terms for a spot-fixing scam next week.

Butt, 27, was jailed for 30 months for his involvement, while 19-year-old bowler Amir received a six-month sentence.

Butt and Amir, along with Mohammed Asif, were all found guilty of plotting to bowl deliberate no-balls in a Test match against England.

The Court of Appeal will hear the case on Wednesday.
