Delhi Agreement 1952 Quora
Although the agreement required the repatriation of Urdu-speaking Biharis to Bangladesh, the Pakistani Government withdrew its promise to establish the Community in Pakistan.  This is where the stranded stateless Pakistani community in Bangladesh was born. A wave of fear spread among people. Pakistan`s prime minister at the time, Liaquat Ali Khan, decided to solve the problem. He made a statement explaining the need for an immediate solution and also proposed that his Indian counterpart meet to study the problem. The two prime ministers met in Delhi on April 2, 1950. They signed an agreement on the protection of minority rights. This pact was known as the Liaquat Nehru Pact. Some of the objectives of the pact were to reduce the fear of religious minorities, put an end to local unrest and create an atmosphere of peace.
Among the prisoners of war, 195 Pakistani military officers detained in India were identified as the main suspects of war crimes. Pakistan insisted that they be released as one of its main demands. It urged several Muslim countries to hold back bangladesh`s recognition until the 195 officers were released.  India supported his repatriation to Pakistan. In the text of the agreement, Kamal Hossain, Minister of Foreign Affairs of Bangladesh, stated that the Delhi Agreement was a trilateral agreement signed on 28 August 1973 between India, Pakistan and Bangladesh; and has been ratified only by India and Pakistan.  It allowed the repatriation of prisoners of war and interned officials detained in the three countries after the Bangladesh Liberation War in 1971. The deal has been criticized because Pakistan failed to bring Urdu spokesmen back to Bangladesh and did not hold accountable 195 senior military officials accused of violating behavior during the war.  The contract came into effect on August 8, 1973 and ended on July 1, 1974. As part of the agreement, UNHCR monitored the repatriation of citizens from Bangladesh and Pakistan. According to the UN, 121,695 Bengals have been relocated from Pakistan to Bangladesh. These included senior Bengali officials and military officers. 108,744 non-Bengali civilians and civil servants were transferred from Bangladesh to Pakistan.
