Papua New Guinea's former justice minister and attorney-general says questions remain over the National Alliance-led government's motive for pushing legislative amendments to the Ombudsman Commission.
Dr Allan Marat resigned last week after publicly criticising controversial amendments to the Ombudsman Commission which many observers say will undermine its integrity.
He says Prime Minister Sir Michael Somare forced him to resign in an angry outburst in front of the government caucus.
Dr Marat says that the current government coalition doesn't allow for MPs to speak out against the views of the leadership.
"'The motive of the majority party within the coalition is not right to some of us. Now we thought that the motive for this amendment it was intended to cover some of the existing misconduct in office charges (against some high level politicians) like failing to lodge annual returns and just misappropriating funds in programmes that were established as a result of government policies."
Dr Marat has withdrawn his Melanesian Liberal Party from the government coalition.
