1990 Pakistani general election

The PPP led by Benazir Bhutto had won a plurality of seats in the 1988 election and Bhutto became Prime Minister. However by 1990 there was discontent over rising lawlessness, allegations of corruption and the failure of the government to fulfill the promises it had made during the 1988 campaign.[5]

The PPP formed an alliance with three other parties, Nifaz Firqah Jafariya, Tekrit-i-Istiqlal and the Pakistan Muslim League (Chatta), running under the name People's Democratic Alliance.[6][7]

By the start of the campaign reports suggested that Bhutto and the PDA were in a stronger position as the caretaker government failed to produce sufficient evidence to prove any charges against her.[8]

At the end of the campaign Bhutto led hundreds of thousands of supporters in a procession in Lahore, while Sharif held a rally for about ten thousand nearby.[9]

On 19 October 2012, the Supreme Court of Pakistan ruled on a petition by Asghar Khan, requesting that the court probe allegations that the 1990 elections had been rigged. The court officially ruled that two Army Generals – Mirza Aslam Baig and Asad Durrani (Head of the ISI) – along with President Ghulam Ishaq Khan – had provided financial assistance to favoured parties.[10] The motive was to deliberately weaken the mandate of the Pakistan Peoples Party. It was believed that the PPP, led by Benazir Bhutto, was a liability to the nation.[11]

IJI won the popular vote by a very narrow margin of only around 100,000 votes, but the narrow victory in the popular vote translated into 106 seats for IJI against the PDA's 44 seats. The popular argument regarding PDA's huge loss of seats is that the PDA's vote, despite being almost equal to that of IJI, was much more spread out whereas IJI's vote bank was more concentrated. This resulted in PDA candidates losing in IJI won seats by narrow margins.
