Papua New Guinea's acting Prime Minister Sam Abal is reported to be unmoved by news that he had been expelled by a group, purporting to be the Enga branch of the ruling National Alliance party.
The newspaper, The National, says a statement announcing the expulsion was signed by Paul Kurai as chairman.
The paper says the United Resource Party, has dumped the minister assisting the Prime Minister on constitutional matters Francis Potape as a member of the party.
Both actions are seen as a response to Mr Abal sacking of the deputy leader of the National Alliance, Don Polye, and the United Resources Party leader, William Duma, as senior ministers.
Mr Abal is yet to name replacements for the two.
