Pakistan's cricket chief Tuesday left for England, where he is expected to meet lawyers in a bid to clear his players of allegations of spot-fixing and fend off demands for an apology. "I am leaving for London on an official trip," Pakistan Cricket Board (PCB) chairman Ijaz Butt told foreign news agency, without giving any details. Reports said Butt and legal adviser Taffazul Rizvi will meet Elizabeth Robertson, the British lawyer representing Pakistani players and the PCB over the spot-fixing allegations. Butt is also expected to meet Scotland Yard officials in a bid to expedite the case that saw Test captain Salman Butt and bowlers Mohammad Asif, Mohammad Aamir and Wahab Riaz interrogated.
