On 21 May 1991, while former Prime Minister Rajiv Gandhi campaigned in Tamil Nadu on behalf of Congress (Indira), a Liberation Tigers of Tamil Eelam (LTTE) female suicide bomber assassinated him and many others by setting off the bomb in her belt by leaning forward while garlanding him. In the elections, Congress (Indira) won 244 parliamentary seats and put together a coalition, returning to power under the leadership of P.V. Narasimha Rao. This Congress-led government, which served a full five-year term, initiated a gradual process of economic liberalisation and reform, which has opened the Indian economy to global trade and investment. India's domestic politics also took new shape, as traditional alignments by caste, creed, and ethnicity gave way to a plethora of small, regionally-based political parties.
