Acting Prime Minister Sam Abal has reportedly dismissed Petroleum Minister William Duma because of doubts over his management of land ownership issues in relation to the PNG LNG project.
Abal was also reported to have dumped Foreign Affairs and Trade Minister Don Polye after ongoing battles between the pair over leadership issues of the Highlands grouping of the National Alliance party.
According to ongoing reports from Radio Australia, Sam Abal said he sacked the two ministers to restore discipline within the government.
The shake up comes after the two ministers defended themselves at a press conference, claiming they were an integral part of the government.
The acting prime minister has not given any indication as to who will be replacing the ministers.
Both men have lashed out at the sacking allegations, claiming they have not been formally notified of their dismissal and so they still remain as cabinet ministers.
Radio Australia reported that Polye only learnt of his sacking through the local media.
Duma questioned the legitimacy of the apparent dismissal, stating there are doubts as to whether an acting prime minister has the powers to commission or decommission ministers.
Back in 2008 Duma criticised PNGIndustryNews.net for reporting on the long delays in issuing petroleum licence renewals and work program approvals.
Abal was due to give a press conference earlier in the week to clarify the situation, but it was cancelled because he was still discussing the changes with his colleagues.
