Islamabad: Newly-elected Prime Minister Nawaz Sharif was administered the oath of office by President Asif Zardari on Wednesday, hours after the PML-N chief was voted to lead the National Assembly and form the government at the centre.
Sharif was elected with 244 votes in the 342-seat parliament, returning him to the prime minister's office for an unprecedented third time.
After being elected to the office of prime minister, Sharif addressed the National Assembly and vowed to fulfill the mandate entrusted upon him by the people of Pakistan.
Nawas Sharif has called for an end to US drone strikes in his first address since being re-elected to the post.
Sharif also talked about bringing about peace in the Sindh and Balochistan areas and promised stronger infrastructure including the uncompleted Khunjerab railway network to China.
Sharif becomes Pakistan's first ever leader to serve as prime minister for the third time following the victory of his Pakistan Muslim League (PML-N) in the May 11 general elections.
He has already served as prime minister for two non-consecutive terms -- the first from Nov 1, 1990 to July 18, 1993 and the second from Feb 17, 1997 to Oct 12, 1999.
Nawaz Sharif was sent into exile in 2000 by then military ruler Pervez Musharraf following the dismissal of his elected government in October 1999.
One of the main tasks of Sharif's government will be presentation of the new budget in the coming few days as Pakistan's new financial year begins from July 1.
