Pakistan's former prime minister, Nawaz Sharif, will stand for parliament in a by-election, a party spokesman says.Mr Sharif's Pakistan Muslim League-N party is currently in negotiations over joining a coalition government.
His party won the second highest number of seats in polls that last week delivered a huge blow to President Pervez Musharraf's allies.
