LONDON - The International Cricket Council's (ICC) anti-corruption unit has been investigating Pakistan's performance in their Sydney Test defeat against Australia in January, it was confirmed on Thursday.

Australia won by 36 runs despite conceding a first-innings deficit and allegations of match-fixing have surrounded the game, with a parliamentary committee in Pakistan summoning top officials to answer questions.

Pakistan Cricket Board (PCB) chairman Ijaz Butt, tour coach Intikhab Alam and former captain Younus Khan were among those summoned after video footage of a PCB meeting was leaked to the media, showing players and former officials raising suspicions about fixing during the Australia tour.
