Chief of Pakistan Tehreek-e-Insaf (PTI) Imran Khan took oath of his National Assembly membership on Wednesday, more than a month after being elected as MNA.

Speaker of the lower house Sardar Ayaz Sadiq, who had defeated the PTI chief on Lahore's NA-122 constituency in May 11 general elections, administered the oath in the session.

He was admitted in the Shaukat Khanam Hospital after falling from a lifter in election-related activity in Lahore last month. He had sustained head and back injuries, and left the hospital after 15 days.
