Reaching the mutual understanding with the
leftist Pakistan Peoples Party (PPP), Khan participated in
presidential elections on a
PPP platform. Khan secured 608 votes in the elections, competing against four other candidates; he was also supported by the conservative
IDA led by
Nawaz Sharif. As president, Khan was marred with political struggle with
Prime Minister Benazir Bhutto who attempted for pushing the bill to reverse the
Eighth Amendment to the Constitution of Pakistan.
Judicial and military appointments Soon after assuming the presidency, President Ghulam Ishaq Khan's conflict arise with Prime Minister Benazir Bhutto's invalid and inappropriate appointments in nation's
court system, which were primarily political rather than meeting merit. Many of
Benazir government's recommendations for judicial appointments were voided and the judicial appointments made by the President himself became a controversial issue in the nation. The appointments of chiefs of staff in the command of the military was another issue where the President Khan was in conflict with the Prime Minister Benazir Bhutto in 1989. President Khan also confirmed
Admiral Yastur-ul-Haq Malik as the
Chief of Naval staff and raised no objections. Although, President Ghulam Ishaq Khan confirmed the nomination of
Admiral Iftikhar Ahmed Sirohey as
Chairman joint chiefs and General
Mirza Aslam Beg as
chief of army staff in 1988, President Khan notably used his presidential powers to retain
Admiral Sirohey as
Chairman joint chiefs and defused any attempts made by Prime Minister Bhutto for
General Beg as the new chairman joint chiefs to control the military. In 1990, President Ghulam Ishaq Khan reportedly denied the term extension of General
Mirza Aslam Beg despite Prime Minister
Nawaz Sharif's urging. He also raised objections and further vetoed the appointment of
Lieutenant-General Hamid Gul, former
DG ISI, as
Chief of Army Staff of
Pakistan Army. Instead, he favoured appointing General
Asif Nawaz as Chief of Army Staff. On the advice of Prime Minister Sharif, he confirmed
Air Chief Marshal Farooq Feroze as
Chief of Air Staff of
Pakistan Air Force.
Dismissal of Bhutto and Sharif governments As economic and
law and order crises deepened, Khan used the
Eighth Amendment to the Constitution of Pakistan to dismiss
Prime Minister Benazir Bhutto's government over
corruption charges and deteriorating
law and order situation and called fresh elections. After holding the
general elections in 1993, he supported
Nawaz Sharif as the Prime Minister and his
IDA government. Problems with Sharif arose with the issue of reversing the
Eighth Amendment when Sharif tried to pass the bill. Eventually, he used the same Amendment to dismiss Sharif's government on similar charges. However, Sharif retaliated by bringing a
lawsuit against him in the
Supreme Court of Pakistan. President Khan's attempt to use the Eighth Amendment was deemed illegal by the Court and Sharif was reinstated as the Prime Minister. The political deadlock persisted and after the joint intervention of the
judiciary and the
military, both Khan and Sharif were forced to resign. ==Philanthropy, retirement and death==
