The leader of the PNG Party, Belden Namah, says he is willing to be Papua New Guinea's next opposition leader although he is still hopeful of becoming Prime Minister.
His comment comes after the People's National Congress leader, Peter O'Neill, was invited by the Governor General to form the next government.
Mr O'Neill appears to have the support of various political parties to lead a coalition government and is expected to be voted as Prime Minister whjen parliament convenes tomorrow.
Mr Namah says he is dumbfounded by his former ally's decision to enter a coalition with former political enemies such as veteran leader Sir Michael Somare
"I am prepared to go into opposition and be an opposition leader with my party. What I stand for is principles. I have certain allegations against those leaders on the other side but I do not wish to state it here. But I hate to see corrupt leaders forming a team together. I stand to fight corruption in my country."
