The England and Wales Cricket Board demanded on Thursday a full and unreserved apology from Pakistan Cricket Board chairman Ijaz Butt for his allegations that England players had engaged in match-fixing. Mr Butt has been advised that if a satisfactory response is not received, legal proceedings will be commenced against him without further notice, an ECB statement said. The threat follows an interview given by Butt to a Pakistan television channel after England lost the third one-day international against Pakistan at the Oval last Friday.
