Minister under the presidential administrations of the Viceroys of India, Archibald Wavell (1946) and Louis Mountbatten (1946-47). Peter Lyon, a reader emeritus in international relations, described Chundrigar as a "close supporter" of Mohammad Ali Jinnah in the Pakistan Movement. Public service in Pakistan Diplomacy and governorships After the partition of India by the act of the British Empire that established Pakistan, Chundrigar endorsed Liaquat Ali Khan's bid for the Premiership and was retained as the Commerce Minister in the administration of Prime Minister Liaquat Ali Khan on 15 August 1947. In May 1948, Chundrigar left the Commerce Ministry and was appointed as Pakistan's Ambassador to Afghanistan. Although his appointment was favorably received in Afghanistan, Chundrigar was at odds with the Afghan government (supported by India as early as 1949) over the issue of Pakistan's north-west border with Afghanistan.

He was appointed as Minister of Law and Justice. During this time, he also acted as a Leader of the Opposition, opposing the mainstream agenda presented by the Republican Party. At the National Assembly, he established his reputation as more of a constitutional lawyer than a politician, and gained a lot of prominence in public for his arguments in favour of parliamentarianism when he pleaded the case of "Maulvi Tamizuddin vs. Federation of Pakistan". Prime Minister of Pakistan (1957) Third Shortest tenure as Prime Minister After the resignation of Prime Minister Suhrawardy in 1956, Chundrigar was nominated as the Prime Minister and was supported by the Awami League, the Krishak Sramik Party, the Nizem-i-Islam Party, and the Republican Party. However, this coalition of mixed parties weakened Chundrigar's authority to run the central government, and divisions within
