The prime minister must enjoy the confidence in the Pratinidhi Sabha before being appointed by the president and shall resign if they are unable to retain the majority in the House.
[5] The position of prime minister of Nepal (Nepali: नेपालको प्रधानमन्त्री, romanized: Nēpālakō pradhānamantrī) in modern form was called by different names at different times of Nepalese history.
[9] Similarly, historian Chittaranjan Nepali writes that the first institution to hold all state powers was the position of Mukhtiyar which was established after King Rana Bahadur Shah returned to Nepal from Varanasi.
[15][16] The character of government in the Kingdom of Nepal was driven from consultative state organ of the previous Gorkha hill principality, known as Bharadar.
[17] There was no single successful coalition government as court politics were driven from large factional rivalries, consecutive conspiracies and ostracization of opponent Bharadar families through assassination rather than legal expulsion.
[24] During Bakhtawar's tenure as the Mul Kaji, on 28 October 1801, the Treaty of Commerce and Alliance was signed between Nepal and East India Company.
[14] By 1797, his relationship with his uncle, who was living a retired life, and who wanted to seek refuge in China on the pretext of meeting the new emperor, had deteriorated to the extent that he ordered his imprisonment on 19 February 1797 and his subsequent murder on 23 June 1797.
Similarly, in mid-1795, he became infatuated with a Maithil Brahmin widow, Kantavati Jha, and married her on the oath of making their illegitimate half-caste son (as per the Hindu law of that time) the heir apparent, by excluding the legitimate heir Prince Ranodyot Shah who was born from his previous marriage with a high caste Chhetri, Queen Subarna Prabha Devi.
[14][31] After the inevitable death of Kantavati, Rana Bahadur suffered a mental breakdown during which he lashed out by desecrating temples and cruelly punishing the attendant physicians and astrologers.
[33] This led to a direct conflict with almost all the courtiers who had pledged a holy oath of allegiance to the legitimate king Girvan Yuddha Bikram Shah.
This conflict eventually led to the establishment of a dual government and to an imminent civil war, with Damodar Pande leading the military force against the dissenting ex-king and his group.
[34][33] Since most of the military officers had sided with Damodar Pande, Rana Bahadur realized that his authority could not be re-established, and he was forced to flee to the British-controlled city of Varanasi in May 1800.
[45] Tribhuvan Khawas (Pradhan), a member of Sher Bahadur's faction, was imprisoned on the re-opened charges of conspiracy with the British that led to the Knox's mission, but for which pardon had already been doled out, and was ordered to be executed.
[50][51] The assassination of Rana Bahadur Shah triggered a great massacre in Bhandarkhal (a royal garden east of Kathmandu Durbar) and at the bank of Bishnumati river.
[52][53] That very night member of Sher Bahadur's faction – Bidur Shah, Tribhuvan Khawas, and Narsingh Gurung – and even King Prithvipal Sen of Palpa, who was under house arrest in Patan Durbar, were swiftly rounded up and killed in Bhandarkhal.
[54][56] Almost one and half months before the massacre, upon Bhimsen's insistence, Rana Bahadur, then 31 years old, had married a 14-year-old girl named Tripurasundari on 7 March 1806, making her his fifth legitimate wife.
[63] On the spot where Rana Bahadur Shah drew his last breath, Bhimsen later built a commemorative Shiva temple by the name Rana-Mukteshwar.
[64] Bhimsen Thapa ruled for 31 years as Mukhtiyar and implemented large number of reforms in agriculture, forestry, trade and commerce, judiciary, military, communications, transportations, slavery, human trafficking and other social evils in his premiership.
[65] Under part 7, Article 76, of the Constitution,[66] the president is required to appoint the leader of the majority party in the House of Representatives as prime minister.
If no majority coalition can be formed within 30 days of the final result of a parliamentary election, the president is required to appoint the leader of the largest party in the chamber.
