The agreement was criticized in India because it contained no war pact or renouncement of guerrilla warfare in Kashmir. After the signing of the agreement, Indian Prime Minister Lal Bahadur Shastri mysteriously died in Tashkent.  Shasti`s sudden death led to persistent conspiracy theories that he was poisoned.  The Indian government refused to downgrade a report on his death claiming that it could harm foreign relations, cause disruption in the country and a violation of parliamentary privileges.  In accordance with Tashkent`s statement, discussions took place at ministerial level on 1 and 2 March 1966. Despite the fact that these talks were unproductive, diplomatic exchanges continued in the spring and summer. The results of these discussions were not obtained due to differences of opinion on the Kashmir issue. The news of Tashkent`s statement shocked the people of Pakistan, who expected India to make more concessions than they got. Things got even worse when Ayub Khan refused to speak and went to solitary confinement instead of announcing the reasons for signing the agreement. Protests and riots took place at various locations in Pakistan. To dispel the anger and concerns of the people, Ayub Khan decided to take the matter before the people on 14 January 1966. This is the difference with Tashkent`s statement that eventually led to the impeachment of Zulfikar Ali Bhutto from the Ayub government, which later founded his own party, the Pakistan People`s Party. Although Ayub Khan was able to satisfy the concerns of the people, Tashkent`s declaration significantly tarnished his image and was one of the factors that led to his downfall.  An agreement signed by Indian Prime Minister Lal Bahadur Shastri and Pakistani President Ayub Khan in the Soviet city of Tashkent to end the Second Indo-Pakistan War on Kashmir. The two countries agreed not only to withdraw their troops from the territory of the other region and to recover their prisoners of war, but also to begin to normalize their diplomatic relations. Unfortunately, the beginning of Indo-Pakistani friendly relations was made more difficult by Shastri`s death a few hours after the signing of the agreement. The agreement has done little to ease the deep hostility between the two countries since independence in 1947 and did not prevent the outbreak of new hostilities in 1970. The Tashkent Declaration was a peace agreement between India and Pakistan, signed on 10 January 1966, which resolved the 1965 Indo-Pakistan war.
