Mansoor Ijaz, the central character in the memo case, revealed on Thursday that he had helped former Pak ambassador Husain Haqqani by delivering the purported secret memorandum to the then US military chief because he had information about the possibility of a military coup in Pakistan.

During the cross-examination before the judicial commission investigating the case, the Pakistani-American businessman said he had been briefed by at least four intelligence networks of different countries after the killing of Al Qaeda chief Osama bin Laden in Abbottabad on May 2, last year.

He said he had obtained the information about actions and reactions of Army Chief Gen Ashfaq Parvez Kayani, President Asif Ali Zardari and the military secretary to the president after the incident, details of foreign visits of the Director General of Inter-Services Intelligence (ISI) and transcripts of conversation between air traffic control staff and the pilots of the US helicopters which raided Osama's compound.

Replying to a question by Salahuddin Mengal, counsel for PML-N lawmaker Gen (retd) Abdul Qadir Baloch, Ijaz said the material he had was sufficient for him to believe that a military coup was imminent.

He said the urgency shown by Haqqani had also supported his belief that a military coup was imminent and then he contacted former US national security adviser Gen James Jones for delivering the memorandum to Admiral Mike Mullen.
