Nepal's leftist political parties have been demanding the abrogation of the 1950 Treaty of Peace and Friendship with India for years. This issue was raised vigorously even after the change in government in 2046. Even now, some forces, including the leftist ones, have not stopped raising the issue of the treaty.

It is understood that the treaty is not in the interest of Nepal. However, the big leftist parties and their leaders have left the issue far from priority. From the Panchayat to the 1950s, the issue of the 1950 treaty with India was a permanent national issue, especially for the leftist parties.

In 2051, when the UML led the government, the leftist leaders demanded that Prime Minister Manmohan Adhikari should make a clear statement with India and abrogate the treaty. When Manmohan, who was leading the first leftist government in Nepal, was preparing for a visit to India, on Chaitra 15, 2051, leftist leader Mohan Chandra Adhikari, CPN Ekta Kendra leader Nara Bahadur Karmacharya, CPN Masal leader Chitra Bahadur KC, and CPN (MLMA) leader Krishna Raj Shrestha submitted a memorandum to the Prime Minister proposing to abrogate the unequal treaty of 1950 and sign a new treaty.

Former UML leader Mohan Chandra and four leftist parties had also declared that the movement for national independence would continue if the unequal treaty was not revoked. The leaders had said, ‘The UML government, like the previous Panchayat and Congress governments, is also hesitant to talk openly with India on the issue of national sovereignty. The current government is also about to kneel. The government should revoke the unequal and humiliating treaty.’ They had put forward the idea that if India rejected the proposal to revoke the treaty, Nepal should automatically invalidate the 1950 treaty by giving a year’s notice. After submitting the memorandum, they expressed dissatisfaction with the Prime Minister’s failure to respond. Mohan Chandra had said, ‘The UML government has also adopted a policy of kneeling with India. What is the difference between this government and the Congress government?’ Mohan Chandra had called the treaty a ‘treaty of slavery.’

Mohan Chandra, the leader of the 2028 armed Jhapa movement, spent more than a decade in prison during the anti-panchayat movement. That is why he was also called the Nelson Mandela of Nepal. Communist League leader Shambhuram argued that it was absurd to seek a national consensus to abrogate the treaty. Masal's KC said that the Prime Minister had shown a sense of inferiority to him that the multi-party system was dependent on India.

Left leader Karmacharya, on the other hand, had maintained that he had no objection to going together even if the Panchas came on the issue of nationality. Left leaders had also claimed that the government's proposal on the use of the Mahakali River, which was put forward as the Mahakali package, was against the national interest.

When the Prime Minister of the minority government formed with the support of the opposition in the majority, was preparing to go to India, the issue of the 1950 treaty, which was raised by the UML itself, had become very complicated. If we raise the issue, how does India view the agenda of a minority government? If we don't, the Prime Minister seems to be in a dilemma of being accused of forgetting the issues he himself raised when he was in the opposition after reaching the government. That is why Prime Minister Manmohan did not give a clear answer while understanding the memorandum of the leftist leaders.
