The PML-N won 129 of the 272 seats in the National Assembly while PTI won only 35.
The commission report said, "Based on the evidence presented before the commission it cannot be said that on an overall basis the elections were not a true and fair reflection of the mandate given by the electorate, despite some lapses by the Election Commission of Pakistan."
