The prime minister of Papua New Guinea has successfully brought an injunction against arrest warrants for himself, the country’s treasurer and its finance minister, claiming the warrants are moves by the opposition leader to stage a coup.

The warrants for the arrest of Peter O’Neill, the treasurer, Don Polye, and the finance minister, James Marape, were issued by a Port Moresby court last November but produced on Monday by the opposition leader, Belden Namah.
