Former president Pervez Musharraf, who had hoped to run in this election, has resigned as chairman of the All Pakistan Muslim League.
The move may be an indication of the end of his bid to contest the elections this year.
Some reports suggest the new party chairman, Mohammad Amjad, may be running for six seats.
Musharraf was banned from politics for life by the Peshawar High Court (PHC) in 2013. He challenged the decision in the SC.
"We are of the considered view that a person who has got not a little respect for whole of the constitution how he will pass through narrow and small compass of articles 62 and 63." ─ PHC verdict
Earlier this month, the SC issued a directive allowing him to file his nomination papers only if he returned and was present in court on June 13 in Lahore, cautioning that the fate of the papers would be subject to the final decision in the present case.
But he failed to return and the SC withdrew its directive.
