Newspapers in Australia are reporting that former prime minister Kevin Rudd is being considered for a top job as a climate change adviser at the United Nations.
The Labor Party is denying the reports, saying that Mr Rudd is committed to standing again for Parliament for the seat of Griffith in next month's elections.
News Ltd papers quote an unnamed source who says Mr Rudd could be made a special envoy or an ambassador reporting directly to the UN secretary-general.
They say the UN "refused to hose down speculation" on the appointment.
The ABC reports Mr Rudd was in New York last week and met UN Secretary-General Ban Ki-moon.
