Copenhagen

• The Prime Minister is in Copenhagen.

• There is an uphill struggle for a deal at Copenhagen - but an ambitious climate deal is vital to Britain's economic prosperity and national security.

• The Prime Minister said last night that:
  
  "It's possible that there can be a deadlock, nobody can doubt that. But it's also, I think, possible to see a way through. But it demands first of all, that the leaders rise to the challenge and don't duck the big decisions; secondly, I think it requires not only that but a higher level of ambition on our part; and thirdly, of course, it's going to be tough negotiations over the next few hours."

• An ambitious climate deal is vital to Britain's economic prosperity and national security; and a huge opportunity for jobs, industry and services. Yes, there will be a cost from avoiding dangerous climate change - but this will be far less than if we delay and ignore the problem.

• We hope for cross-party support on action at Copenhagen. But a deal at Copenhagen has to be matched by action at home - and the Conservatives have flip-flopped on nuclear and David Cameron's councils have rejected 60 per cent of wind energy applications. As the Prime Minister said in the House of Commons last week, it seems that the Tories are "all wind and no turbines".
