After a tediously slow count, Pakistan election officials Friday announced Khan's Pakistan Tehreek-e-Insaf (PTI) party won 109 of the 269 seats being contested in the National Assembly.
The election Wednesday gave his nearest rival, Shahbaz Sharif's Pakistan Muslim League 63 seats. Sharif who heads the party of jailed ex-prime minister Nawaz Sharif has rejected the results charging widespread fraud and manipulation, AP reported.
Khan declared his victory on Thursday and dismissed the allegations of fraud calling it the most transparent election in Pakistan's history.
Third place went to the left of center Pakistan People's party with 39 seats. Results from 20 seats were still being counted.
