Question: How old was Zulfikar's wife when their daughter was born? Passage:Shah Nawaz Bhutto, a direct descendant of Muhammad Khan, came to prominence during the British Raj as a dewan of the princely state of Junagadh in south-western Gujarat in India. During the Partition of India in 1947, the Muslim Nawab of Junagarh wanted to accede his state to the newly created Pakistan, but he faced rebellion by the population of Junagadh, majority of whom were Hindus. The Indian government thwarted Junagadh's accession to Pakistan, and the Bhuttos fled to Sindh in modern-day Pakistan. Shah Nawaz Bhutto moved to Larkana District in Sindh, where his land-ownership made him one of the wealthiest and most influential people in Sindh. Beginning the political dynasty, Shah Nawaz's third son Zulfikar Ali Bhutto (1928-1979) founded the Pakistan People's Party (PPP) in 1967 and served as President and Prime Minister. He married an Iranian-Kurdish woman named Nusrat Bhutto. His daughter, Benazir (1953-2007), also served as Prime Minister, while Benazir's husband, Asif Ali Zardari, later served as president from 2008 to 2013. The Bhuttos continue to dominate the leadership of the PPP. Benazir's son Bilawal Bhutto Zardari became co-chairperson in 2007.
