[3] In 1955 he returned and formed the United Democratic Party, and following the installation of the Panchayat system he fought for its end, for which he was jailed.

Following his release, he went into self-imposed exile, but eventually returned to Nepal and was elected a member to the Rastriya Panchayat.

He was an effective organizer, and was able to get support from people he knew through his medical practice and ex-servicemen from India.

Singh's most serious clashes were with the local zamindars, who were extremely unpopular among the peasantry for allegedly bringing in Indian goodas to loot their villages in 1949–50.

When the fighting began, these zamindars sent their families to India and started cooperating with the Bada Hakim of Bhairawa.

For example, after storming the house of zamindar Bhubaneshwar Shukla, nine government soldiers who were inside were gunned down immediately for allegedly mistreating rebels previously, and fifty Indian goondas who were there tried to escape but were killed by the villages who helped Singh with the siege.

Singh was asked to stop the fighting, he refused to accept the Delhi Accord, and was dissatisfied with the leadership of Nepali Congress.

The Raksha Dal was an auxiliary security force set up immediately after the revolution, mostly from members of the Muktisena, Nepali Congress' militant wing.

This arrest led to a revolt of the Raksha Dal in Kathmandu, who freed both Ram Prasad Rai and K.I.

[7] He also did not receive any support from the Chinese government, and apparently did not meet either Mao Zedong or Zhou Enlai.

It is also alleged that Singh formed the UDP with funding from King Mahendra, to try to counter the influence of Nepali Congress.

Singh was made Prime Minister by Mahendra, replacing his predecessor Tanka Prasad Acharya of the Nepal Praja Parishad.

[6] With Nepali Congress forming a government, the second largest party, the right-wing Gorkha Parishad, who were supported and made up by the Ranas, became the opposition.

[8] This United Front was, according to Singh, formed to guard Nepal's highest values, like nationalism, democracy, good government and social justice.

[9] In April 1963, he stated he planned to launch a satyagraha to agitate for the restoration of parliamentary democracy.

Eventually, after negotiating with the King to try to gain some form of political office, in March 1964 he announced the satyagraha would go ahead, leading to his arrest.
