Prime Minister of India
After the end of Rao's tenure in May 1996, the nation saw four prime ministers in a span of three years, , two tenures of Atal Bihari Vajpayee; one tenure of H. D. Deve Gowda from 1 June 1996 to 21 April 1997; and one tenure of I. K. Gujral from 21 April 1997 to 19 March 1998. The government of Prime Minister Vajpayee—elected in 1998—took some concrete steps. In May 1998—after a month in power—the government announced the conduct of five underground nuclear explosions in Pokhran. In response to these tests, many western countries, including the United States, imposed economic sanctions on India, but, due to the support received from Russia, France, the Gulf countries and some other nations, the sanctions—were largely—not considered successful. A few months later in response to the Indian nuclear tests, Pakistan also conducted nuclear tests. Given the deteriorating situation between the two countries, the governments tried to improve bilateral relations. In February 1999, the India and Pakistan signed the Lahore Declaration, in which the two countries announced their intention to annul mutual enmity, increase trade and use their nuclear capabilities for peaceful purposes. In May 1999, All India Anna Dravida Munnetra Kazhagam withdrew from the ruling National Democratic Alliance (NDA) coalition; Vajpayee's government, hence, became a caretaker one after losing a motion-of-no-confidence 269–270, this coincided with the Kargil War with Pakistan. In the subsequent October 1999 general election, the BJP-led NDA and its affiliated parties secured a comfortable majority in the Lok Sabha, winning 299 of 543 seats in the lower house.
