However, leaders of other political parties believe Qadri decided not to contest polls, expected to be held in May, to retain his Canadian nationality.

Qadri, who heads the Tehrik Minhaj-ul-Quran, has made conflicting statements on whether his Pakistan Awami Tehrik party will participate in the general election.
The ruling Pakistan People’s Party and main opposition PML-N have questioned why a person who does not want to become part of the electoral process is pressing for electoral reforms.
