BlackBerry maker Research in Motion (RIM) has said it will not release data regarding a memo that said President Asif Ali Zardari had feared a military coup last year, it was reported here. Geo News reported that the BlackBerry maker has refused to release data related to the memo that led to the stepping down of the country\'s US envoy Hussain Haqqani and a festering row between the military and the political leadership. The phone manufacturer, based in Canada, has said that their privacy laws prohibit disclosure of a customer\'s data to any other party without the consent of the parties concerned, hence Pakistan cannot have the information. Pakistani-American businessman Mansour Ejaz had reportedly forwarded the memo to then US military chief General Mike Mullen in May last year. RIM said that their response was to a sealed letter from the attorney general of Pakistan, the media report said.
