The climate deal planned for Copenhagen in 10 weeks' time is in grave danger of failure, the prime minister has said.
Gordon Brown has become the first world leader to offer to go to the Danish capital to help seal the deal.
He told Newsweek magazine there was no second chance to undo "catastrophic damage" to the environment if "we miss the opportunity to protect the planet".
The former Deputy Prime Minister, John Prescott helped negotiate the Kyoto Climate Protocol on global warming, and now represents the Council of Europe on the issue.
He told Martha Kearney on Radio 4's The World At One that Gordon Brown was right to sound a warning about the difficulties in getting agreement at Copenhagen.
