Girija Prasad Koirala

In Nepal's first multiparty democratic election in 1991, Koirala was elected as a member of parliament from the Morang-1 and Sunsari-5 constituencies. The Nepali Congress won 110 of the 205 seats in the Pratinidhi Sabha (House of Representatives), the lower house of parliament. He was subsequently elected as the leader of the Nepali Congress parliamentary party and was appointed as Prime Minister by King Birendra.[9]

During his first term, the House of Representatives enacted legislation to liberalize education, media and health sectors in the country. The government also founded the Purbanchal University and the B.P. Koirala Institute of Health Sciences(BPKIHS) in the Eastern Development Region and granted licenses to the private sector to run medical and engineering colleges in various parts of the country. The government also undertook the construction of the B.P. Koirala Memorial Cancer Hospital in Bharatpur, Nepal with assistance from the government of China. In November 1994, he called for a dissolution of parliament and general elections after a procedural defeat on the floor of the House when 36 members of parliament (MPs) of his party went against a government-sponsored vote of confidence. This led to the Communist Party of Nepal (Unified Marxist–Leninist)-led coalition coming to power in the elections that followed.[9]

Koirala took over as Prime Minister from Surya Bahadur Thapa following the collapse of the coalition government led by Thapa. Koirala first headed a Nepali Congress minority government until 25 December 1998, after which he headed a three-party coalition government with the Communist Party of Nepal (UML) and the Nepal Sadbhawana Party.

Koirala became Prime Minister in 2000 for his third term following the resignation of Krishna Prasad Bhattarai, under whose leadership the Nepali Congress Party had won the parliamentary election. The party had won claiming that Krishna Prasad Bhattarai would be the Prime Minister, but Koirala led a group of dissident MPs and forced Bhattarai to resign or face a no-confidence motion. At that time Nepal was fighting a civil war against the Communist Party of Nepal (Maoist). Koirala resigned in July 2001[9] after which the military was mobilized in the civil war for the first time, something Koirala had unsuccessfully attempted to do while in office. He was replaced by former Prime Minister Sher Bahadur Deuba, who was elected by a majority of members of the Nepali Congress.

After the Loktantra Andolan and the reinstatement of the Nepal House of Representatives, Pratinidhi Sabha, on 24 April 2006, Koirala was selected to become Prime Minister by the leaders of the Seven Party Alliance. The reinstated House of Representatives passed laws to strip the King of his powers and bring the Army under civilian control. Following the promulgation of the interim constitution, Koirala, as the Prime Minister, became the interim head of state of Nepal.

On 1 April 2007, Koirala was re-elected as Prime Minister to head a new government composed of the SPA and the CPN (Maoist). Following the April 2008 Constituent Assembly election, the Constituent Assembly voted to declare Nepal a republic on 28 May 2008. Koirala, speaking to the Constituent Assembly shortly before the vote, said that "we have a big responsibility now"; he said that Nepal was entering a "new era" and that "the nation's dream has come true".[11]

Koirala continued again as the prime minister of Nepal for a fifth term. In the discussions on power-sharing that followed the declaration of a republic, the Nepali Congress proposed that Koirala become the first President of Nepal; however, the CPN (Maoist), which had emerged as the strongest party in the Constituent Assembly election, opposed this.[12]

At a meeting of the Constituent Assembly on 26 June 2008, Koirala announced his resignation, although it would not be finalized until after the election of a President, to whom the resignation had to be submitted.[13]

Koirala was present for the swearing in of Ram Baran Yadav, the first President of Nepal, on 23 July 2008.[14] He submitted his resignation to Yadav later on the same day.[15] CPN (M) Chairman Prachanda was elected by the Constituent Assembly to succeed Koirala on 15 August 2008; Koirala congratulated Prachanda on this occasion.[16]

Towards the end of his life, Koirala was leading a democratic front composed of parties that supported and promoted liberal democratic principles and aspired to establishment of a long-term democratic form of governance in Nepal.
