The prime minister of India is the head of government of the Republic of India. Executive authority is vested in the prime minister and his chosen Council of Ministers, despite the president of India being the nominal head of the executive. The prime minister has to be a member of one of the houses of bicameral Parliament of India, alongside heading the respective house. The prime minister and the cabinet are at all times responsible to the Lok Sabha.

He took office after the assassination of his mother, then–prime minister Indira Gandhi, to become at the age of 40 the youngest Indian prime minister. He served until his defeat at the 1989 election, and then became Leader of the Opposition, Lok Sabha, resigning in December 1990, six months before his own assassination.

The assassination of Rajiv Gandhi, former prime minister of India, occurred as a result of a suicide bombing in Sriperumbudur in Tamil Nadu, India on 21 May 1991. At least 14 others, in addition to Gandhi and the assassin, were killed. It was carried out by 22-year-old Kalaivani Rajaratnam, a member of the banned Sri Lankan Tamil separatist rebel organization Liberation Tigers of Tamil Eelam (LTTE). At the time, India had just ended its involvement, through the Indian Peace Keeping Force, in the Sri Lankan Civil War.
