Deposed Australian prime minister Kevin Rudd may join the United Nations as a top-level climate change adviser, a report said on Thursday. The Daily Telegraph, quoting a diplomatic source, said UN Secretary-General Ban Ki-moon was considering creating the role for Rudd, who was ousted one month ago by Julia Gillard in a party coup. 'He could be made a special envoy or ambassador reporting directly to the secretary-general,' said the source, who was not named. Rudd spent several days in New York last week meeting with UN officials, but diplomats there told the Telegraph that no terms or start date had been fixed. The ex-leader has proved a distraction to the government's campaign for August 21 elections, and attracted widespread media attention when he appeared in his Brisbane electorate on Wednesday. Gillard has promised Rudd a cabinet position if the Labor government is re- elected, but a UN appointment would see Rudd leave parliament and relocate to New York. The Daily Telegraph said a UN spokesman in New York refused to confirm any possible move. 'We don't comment on appointments until they're announced,' he said.
