To assume office, Khan will face a vote in parliament — perhaps as early as Saturday — in which he will have to defeat a rival candidate fielded by the opposition, AP reported.
Khan's Tahreek-e-Insaf party won the most parliament seats in last month's general elections — 115 — but fell short of a majority in the 342-seat assembly, requiring it to form a coalition. Many lawmakers who won as independents in the July 25 vote have joined his coalition.
Tahreek-e-Insaf leader Arif Alvi, a lawmaker elected from Karachi, said Khan was formally nominated at a party meeting in Islamabad on Monday. He was unanimously endorsed, said Shah Mahmood Qureshi, a former foreign minister and party deputy leader.
But Khan is likely to face tough opposition from the Pakistan Muslim League of ousted prime minister Nawaz Sharif and other parties, which allege vote-rigging in last month's elections. Sharif is currently appealing a 10-year prison sentence for corruption and the party is led by his brother, Shabaz Sharif.
Qureshi insisted the opposition would not be able to undermine the new government and quoted Khan as saying during Monday's meeting that all they can do is "create a rumpus."
Also Monday, the Pakistan Muslim League convened in the eastern city of Lahore to discuss the formation of the provincial government in Punjab. It's relying on assembly members who won seats as independents to side with it in the 371-seat provincial assembly. The party won 129 seats there.
Khan's party, which won 123 seats in Punjab, is also aspiring to form the provincial government, saying it also has won over many independents.
