Ashfaq Parvez Kayani, NI(M), HI (Urdu: اشفاق پرویز کیانی , born April 1952) is a four-star general in the Pakistan Army, and the current Chief of Army Staff of the Pakistan Army. He replaced General Pervez Musharraf as the Chief of Army Staff and the commandant of the army on November 29, 2007. General Kayani is the former Director General of Pakistan's Inter-Services Intelligence (ISI), and Director General of Military Operations (MO). On 24 July 2010, Prime Minister Yousaf Raza Gillani extended Kayani’s term as Chief of the Army Staff by three years, making him the first four-star general to receive a term extension from any democratic government. In 2008, Newsweek named him the 20th most powerful person in the world.
Corps Commander Rawalpindi
Kayani was promoted as Lieutenant General in September 2003, and was given the command of the X Corps in Rawalpindi. The promotion indicated Musharraf's significant trust in Kayani, since an army chief cannot build an army coup without the help of the X Corps commander. Kayani led the corps until October 2004, when he was transferred to the ISI as its chief.
During Kayani's tenure at the X Corps, he led the successful investigation of the two back-to-back suicide attacks against Musharraf in December 2003. It is believed that Kayani won the trust of Musharraf after the investigation, and a prelude to Kayani's promotion to the sensitive position of ISI chief. He was awarded Hilal-e-Imtiaz, the civilian medal, for his achievement.
Inter-Services Intelligence
In October 2004, Ashfaq Kayani was made the director general of Inter-Services Intelligence (ISI), in place of General Ehsan ul Haq, who was promoted as the Chairman Joint Chiefs of Staff Committee. Kayani led the ISI during a bleak period, with insurgencies in North-West Pakistan and Balochistan, Abdul Qadeer Khan's nuclear proliferation scandal, and waves of suicide attacks throughout Pakistan emanating from the northwestern tribal belt. In his final days at the ISI, he also led the talks with Benazir Bhutto for a possible power sharing deal with Musharraf. In October 2007, after three years, he was replaced at the ISI by Lt Gen Nadeem Taj.
Kayani was also present at the March 2007 meeting that took place between Musharraf and Chief Justice Iftikhar Muhammad Chaudhry, when the former military ruler informed the top judge that he was suspended. Accounts of that meeting narrated that Kayani was the only one among Musharraf’s aides who did not speak a word.
Chief of Army Staff
In October 2007, Kayani was promoted as a full general, and made the Vice Chief of Army Staff. At the time of promotion, Kayani superseded one officer, Lt Gen Khalid Kidwai who was on an extension for a year. He took over as the new army chief of Pakistan Army after Musharraf's retirement on November 28, 2007. The ceremony was held at the sports stadium near General Headquarters, Rawalpindi. Kayani is the first officer in the history of Pakistan who held the position of DG ISI and then went on to become the Chief of Army Staff (COAS). The last time a Director General of the ISI was to be made army chief in 1999, the Army staged a bloodless coup to reinstate the proposed outgoing Chief of Army Staff, General Pervez Musharraf.
