LAHORE - The Pakistan Cricket Board, on advice from Cricket Australia, has changed the hotels of the touring team in Dubai and Abu Dhabi. Reports suggested that the CA raised security concerns for Ricky Ponting's team for their stay in the hotels in the two cities. The Australians in the first phase of the series, postponed a number of times, will play five ODIs later this month. Reports said that Zakir Khan, PCB's director operations has been sent to Dubai to make suitable arrangements for the coming series. "The board had booked the Marriot hotel for both teams but now another hotel has been chosen for the Australians who reach Dubai on the 18th straight from South Africa," a report said. Security has been a key issue with the Australians since Pakistan agreed to shift the series of five One-day games and a Twenty20 International to the emirate states due to security concerns expressed by the Australians about playing in Pakistan. PCB Chairman Ijaz Butt confirmed that no memorandum of understanding had been signed as yet with Cricket Australia for the series due to some outstanding issues. "We are confident the MoU would be signed in next few days as soon as we finalise sponsorship for the series and some security issues raised by the Australians are sorted out," Butt said. The Australians have avoided signing the MoU until the security plan approved for the series by the Pakistan and Emirates Cricket Boards is cleared by security experts hired by CA. To ensure foolproof security for the series and the Australians stay in the emirates, Pakistan has even decided to hire 100 private bodyguards for security duties. It has also sent a two-man security team to Dubai to coordinate with the local police authorities in both cities.
