The Prime Minister's Office (Urdu: دفترِ وزیرِ اعظم) is the principal workplace of the Prime Minister of Pakistan and is headed by the Principal Secretary to the Prime Minister of Pakistan.

1972 Sindhi Language Bill was introduced by the Chief Minister Mumtaz Bhutto on 3 July 1972, in the Sindh Assembly, Pakistan. The 1972 Language violence in Sindh occurred starting on 7 July 1972, when the Sindh Assembly passed the Sind Teaching, Promotion and Use of Sindhi Language Bill, 1972 which established Sindhi language as the sole official language of the province resulting in language violence in Sindh. Due to the clashes, Prime Minister Zulfikar Ali Bhutto explained that this bill is not against Urdu language. Later an ordinance was also promulgated to clarify it. The original bill as passed by the Sindh Assembly on 7 July 1972 is still in place.

Syed Mohammad Ali Chowdhury Bogra (19 October 1909 – 23 January 1963) was a Pakistani politician and diplomat who served as the third prime minister of Pakistan from 1953 to 1955. He was appointed in this capacity in 1953 until he stepped down in 1955 in favour of his federal finance minister Chaudhri Muhammad Ali.

After his education at the Presidency College at the University of Calcutta, he started his political career on Muslim League's platform and joined the Bengal's provincial cabinet of then-Prime Minister H. S. Suhrawardy in the 1940s. After the independence of Pakistan in 1947, he joined the foreign ministry as a diplomat and briefly tenured as Pakistan's ambassador to Burma (1948), High Commissioner to Canada (1949–1952), twice as ambassador to the United States, and as ambassador to Japan (1959–1962).

Huseyn Suhrawardy (8 September 1892 – 5 December 1963) was a Pakistani politician and statesman who served as the fifth prime minister of Pakistan from 1956 to 1957 and before that as the prime minister of Bengal from 1946 to 1947. In both Pakistan and Bangladesh, he is regarded as a patron of separate homeland for South Asian Muslims, for which he is revered as one of the leading founding statesmen of Pakistan; and also as the pioneer of the Bengali civil rights movement in Bangladesh.

Born in 1892 at Midnapore, Bengal, Suhrawardy was a scion of one of Bengal's most prominent Muslim families, the Suhrawardys. He studied law at the University of Oxford, and joined the independence movement during the 1920s as a trade union leader in Calcutta, initially associated with the Swaraj Party. He joined the All-India Muslim League and became one of the leaders of its Bengal branch. Suhrawardy was elected to the Bengal Legislative Assembly in 1937 and led the Muslim League to decisively win the 1946 provincial general election in Bengal, serving as the last prime minister of Bengal until the partition of India. His premiership was notable for his proposal to create a separate and united Bengal — supported by the Muslim League but opposed by the Indian National Congress — and failing to prevent the Great Calcutta Killings. In 1947, the Bengal Assembly voted to partition the province. Suhrawardy briefly remained in India after partition to attend to his ailing father and manage his family's property. He eventually moved to Pakistan and divided his time between Karachi (Pakistan's federal capital) and Dhaka (capital of East Pakistan).

Sir Khawaja Nazimuddin KCIE (19 July 1894 – 22 October 1964) was a Pakistani politician and statesman who served as the second governor-general of Pakistan from 1948 to 1951, and then as the second prime minister of Pakistan from 1951 to 1953.

Born into an aristocratic Nawab family in Bengal, he was educated at Aligarh Muslim University before pursuing post-graduation studies at the Cambridge University. Upon returning, he embarked on his journey as a politician on the platform of the All-India Muslim League. His political career initially revolved around advocating for educational reforms in Bengal, later focusing on supporting the Pakistan Movement, a campaign for a separate Muslim homeland. Nazimuddin rose to popularity as the party's principal Bengali leader and a close associate of Muhammad Ali Jinnah. He served as Prime Minister of Bengal in British India from 1943 to 1945, and later as the 1st chief minister of East Bengal in independent Pakistan from 1947 to 1948.

Benazir Bhutto (21 June 1953 – 27 December 2007) was a Pakistani politician and stateswoman who served as the 11th prime minister of Pakistan from 1988 to 1990, and again from 1993 to 1996. She was the first woman elected to head a democratic government in a Muslim-majority country. Ideologically a liberal and a secularist, she chaired or co-chaired the Pakistan People's Party (PPP) from the early 1980s until her assassination in 2007.

Of Sindhi, Persian and Kurdish parentage, Bhutto was born in Karachi to the politically-significant aristocratic Bhutto family. She studied at Harvard University and the University of Oxford, where she served as President of the Oxford Union. She returned to Pakistan in 1977 during her father Zulfikar Ali Bhutto's socialist government, shortly before her father was ousted in a military coup and later executed. Bhutto and her mother, Nusrat Bhutto, took control of the PPP and led the country's Movement for the Restoration of Democracy (MRD). Bhutto was repeatedly imprisoned by Zia-ul-Haq's military government and self-exiled to Great Britain in 1984. She returned in 1986 and — influenced by Thatcherite economics — transformed the PPP's platform from a socialist to a liberal one, before leading it to victory in the 1988 election. As prime minister, her attempts at reform were stifled by conservative and Islamist forces within the country, including President Ghulam Ishaq Khan and the Pakistani military. Her administration, having been accused of corruption and nepotism, was dismissed by Khan in 1990 with the following election being rigged by Intelligence services to ensure a victory for the conservative Islamic Democratic Alliance (IJI), at which point Bhutto became the Leader of the Opposition.
