After their release Khair Bakhsh Marri and Sherof Marri decided to opt out of Parliamentary politics while Mir Ghaus Bakhsh, Mir Gul Khan Nasir and Ataullah Mengal joined Wali Khan's National Democratic Party or NDP. But after the Saur Revolution, Mir Ghaus Bakhsh and Wali Khan developed differences and Mir Ghaus Bakhsh along with Mir Gul Khan formed the PNP while Ataullah Mengal went into exile in London.
After some time Mir Ghaus Bakhsh and Mir Gul Khan Nasir had a falling out due to which Gul Khan (who was the President of PNP Balochistan) resigned from his post in the party.
