Papua New Guinea's Attorney General has resigned after upsetting the Government with a series of comments, including criticism of controversial legislation that some say will undermine the Ombudsman Commission.
The Prime Minister, Sir Michael Somare, gave Allan Marat an ultimatum at a Tuesday meeting after Mr Marat publicly questioned the bill.
The newspaper, The National, says Mr Marat had also raised concerns over a controversial Chinese-run nickel mine and the benefits for PNG from the ExxonMobil Liquefied Natural Gas project.
He was criticised for last month visiting one of PNG's most notorious criminals, William Kapris, who is in jail and faces court over a series of bank robberies in 2008.
Mr Marat has not indicated whether he will stay with the government or move to the Opposition.
Meanwhile about 5,000 people marched on Parliament on Tuesday, presenting a petition of 20,000 signatures calling for a stop to the Ombudsman Commission amendments.
