Papua New Guinea's opposition leader has accused the prime minister, Peter O'Neill, of abuse of office for personal gain.
Don Polye has issued a statement alleging that Mr O'Neill put pressure on the board of PNG Power Limited for it to sell land in Boroko cheaply and without the proper tendering and procurement processes.
Mr Polye also says the prime minister always belittles issues of national importance with personal attacks at many forums including on the floor of Parliament.
The two politicians accuse each other of lying, with Mr Polye insisting that he has been up front debating many government policies and decisions.
Mr Polye says he doubts whether Mr O'Neill was genuine when he called for constructive debates.
