No results were achieved as a result of these discussions, due to differences of opinion on the Kashmir issue. The news of the Tashkent declaration shocked the people of Pakistan who expected more concessions from India than they received. Things got even worse when Ayub Khan refused to speak out and went to solitary confinement instead of announcing the reasons for signing the agreement. Protests and riots broke out in different locations across Pakistan.  To appease the anger and concerns of the people, Ayub Khan decided to take the matter to the people on January 14, 1966 by addressing the nation. It was the difference on the Tashkent declaration that eventually led to Zulfikar Ali Bhutto`s withdrawal from Ayub`s government, who later founded his own party called Pakistan People`s Party. After the signing of the agreement, Indian Prime Minister Lal Bahadur Shastri died mysteriously in Tashkent.  Shastri`s sudden death led to stubborn conspiracy theories that he was poisoned.  The Indian government refused to downgrade a report on his death claiming it could damage foreign relations, cause disruption in the country and a breach of parliamentary privileges.  The Tashkent Declaration was a peace agreement between India and Pakistan to resolve the 1965 Indo-Pakistani War (August 5, 1965 – September 23, 1965).
It was signed in Tashkent, the capital of Uzbekistan, which in turn was part of one of the republics composed of the USSR. The main objective was to re-establish economic and diplomatic relations in the countries concerned, to stay away from the internal and external affairs of the other and to work for the advancement of bilateral relations. The Tashkent Declaration was a peace agreement signed on January 10, 1966 between India and Pakistan, which resolved the Indo-Pakistani War of 1965. Peace had been achieved on September 23 thanks to the intervention of external powers that pushed the two nations to a truce, fearing that the conflict would escalate and attract other powers.   VI The Prime Minister of India and the President of Pakistan agreed to consider measures to restore economic and trade relations, communications and cultural exchanges between India and Pakistan and to take measures to implement existing agreements between India and Pakistan. . . .
