On the other hand, Pakistan’s anti-corruption body on Friday had summoned Imran Khan in connection with an ongoing inquiry into his alleged misuse of government’s helicopters. It looks that the road ahead for Prime Minister in-waiting Imran Khan is not going to be an easy one.

The National Accountability Bureau (NAB) sent summons to Imran on August 7 as Khyber Pakhtunkhwa has a provincial government headed by Khan's PTI party since 2013. It has been alleged he had used two helicopters belonging to the Khyber Pakhtunkhwa government privately for 74 hours, causing a loss of Rs 2.1 million to the national exchequer.

It is said that in politics there are no permanent enemies. In Pakistan too, two main rival parties have now joined hands to challenge Imran Khan’s candidature for the Prime Minister as his political party doesn’t have absolute majority. The PML-N and PPP will now field their joint candidate for the post of Prime Minister to challenge Imran Khan in the National Assembly of Pakistan.

Imran Khan's party had won 116 out of 270 seats and he can form a government only by taking support from some independents and minor parties.

Miriam Aurangzeb, the spokesperson of PML-N said, "It is a coalition which is against the rigging of elections, and where all political parties were not given equal opportunities to participate in the election.”

However, it would be difficult for the opposition to challenge the appointment of Imran Khan as the Prime Minister in Parliament as they are short of numbers. A few other nationalists and religious parties have also this coalition which has been named the All Party Conference.
