After the creation of Pakistan in 1947, he was elected to the Central Legislative Assembly. But soon was posted to Burma as an Ambassador in 1948. After that in 1949, he was appointed as High Commissioner to Canada and as Ambassador to United States, in 1952. He was then, appointed as Prime Minister in April 1953, after the dismissal of Khawaja Nazimuddin by the Governor General, Ghulam Mohammad. Bogra, immediately, started concentrating on the task of formulating a constitution for the state of Pakistan; however he approached the issue as a technocrat, rather than as a politician. In order to complete his task, he introduced the famous “Bogra formula,” that required the creation of a bicameral legislature. Even though the plan gained popularity, any progress on it was halted in 1954 when Gulam Mohammad dissolved the first legislature of Pakistan.
