The England captain Andrew Strauss has criticised the International Cricket Council for not doing enough to fight corruption in the sport.
Three Pakistan players have been sentenced to jail terms for their part in spot-fixing during a Test against England at Lord's last year.
But Strauss says there are still a lot of questions to be answered because the corruption was exposed by the News of the World and not cricketing bodies.
He says the ICC could be doing much more and called its anti-corruption unit a "toothless tiger", saying it couldn't operate sting operations like the newspaper did because it didn't have the resources needed.
Strauss says the scandal won't affect the two teams' upcoming Test and one-day series.
England will play Pakistan in Dubai in January, the first meeting of the two teams since the spot-fixing problems which led to corruption charges against Salman Butt, Mohammad Asif and Mohammad Aamer.
