by President Zia's widow, Begum Khaleda Zia, parliamentary elections were held on schedule in May 1986. The Jatiya Party won a modest majority of the 300 elected seats in the National Assembly. The participation of the Awami League—led by the late President Mujib's daughter, Sheikh Hasina Wajed—lent the elections some credibility, despite widespread charges of voting irregularities. Ershad resigned as Chief of Army Staff and retired from military service in preparation for the 1986 presidential elections, scheduled for October. Protesting that martial law was still in effect, both the BNP and the AL refused to put up opposing candidates. Ershad easily outdistanced the remaining candidates, taking 84% of the vote. Although Ershad's government claimed a turnout of more than 50%, opposition leaders, and much of the foreign press, estimated a far lower percentage and alleged voting irregularities. In November 1986, his government mustered the necessary two-thirds majority in the National Assembly to pass the seventh constitutional amendment bill, protecting Ershad and his regime from prosecution for actions taken under the years of military rule. Martial law was subsequently lifted on 11 November and the opposition parties took their elected seats in the National Assembly. In July 1987, however, after the government hastily pushed through a controversial legislative bill to include military representation on local administrative councils, the opposition walked out of Parliament. Passage of the bill helped spark an opposition movement that quickly gathered momentum, uniting Bangladesh's opposition parties for the first time. The government began to arrest scores of opposition activists under the country's Special Powers Act of 1974. Despite these arrests, opposition parties continued to organise protest marches and nationwide strikes. In order to prevent a 72-hour strike planned for 29 November, Ershad declared a state of emergency on 27 November. Parliament was dissolved on 6 December, and fresh elections scheduled for March 1988. All major opposition parties refused government overtures to participate in these polls, maintaining that the government was incapable of holding free and fair elections. Despite the opposition boycott, the parliamentary elections proceeded. The ruling Jatiya Party won 251 of the 300 seats. The Parliament, while still regarded by the opposition as an illegitimate body, held its sessions as scheduled, and passed numerous bills, including, in June 1988, a the controversial eighth amendment to the Constitution, which made Islam the state religion, in contrast to the original secular nature of the Constitution.
