Meanwhile, Chief Minister of Punjab Shehbaz Sharif on Tuesday met Former Interior Minister Chaudhry Nisar Ali Khan .
The two leaders discussed internal party issues and the domestic political scenario in the meeting.
Nisar's strongly-worded statement comes at a time when the PM, along with the foreign minister and foreign secretary, is in the United States to attend the 72nd session of the United Nations General Assembly (UNGA).
Nisar is one of the oldest members of the PML-N his association with the party spans over nearly three decades.
Earlier this year in July, speculations about the former interior minister's decision to part ways with the party were rife but both senior PML-N leaders and Nisar denied the reports as mere rumours.
