Imran Khan, a former prime minister of Pakistan, has reaffirmed his appeal for early elections in the wake of his party's winning a key provincial assembly in a surprise upset during a recent by-election. In the by-elections held on Sunday, Imran Khan's Pakistan Tehreek-e-Insaf won 15 of the 20 seats for the provincial parliament, while the Pakistan Muslim League-Nawaz (PML-N) received only four. A candidate running alone won one of the seats.
