Ed Miliband (Labour)
On Europe, Labour Members think that it is in the national interest for Britain to be strongly engaged in Europe on issues from terrorism to climate change, and from the global economy to human trafficking. We all know that the Prime Minister is in a slightly tricky predicament on Europe. He has his old friends and his new friends on the Front Bench. I want to tell him very sincerely that we are here to help him. We know that he held some pretty strong views on Europe in the past, but we are willing to ignore his previous convictions, just as long as he is as well.
Thirdly, on the Cancun conference on climate change, I have to say—I think the Prime Minister will agree—that the prospects do not look bright for completing the unfinished work of Copenhagen. May I urge him on to show greater leadership on this issue— [Interruption.] Leadership, which is not just about some huskies, but is real leadership on this issue. Can he say what he will be doing personally to advance a deal on finance, which is a crucial precondition of progress and a key objective of the Cancun summit?
The Prime Minister has obviously not learned the lesson, because he left the summit bragging again, saying that he was a Euroscpetic. When will he recognise that anti-European bluster and PR are no substitute for a decent, engaged European policy? He should be leading the way on climate change, signing the directive on human trafficking, and working with European Governments to sustain demand in the global economy. The Prime Minister may have abandoned some of his previous convictions, but his rehabilitation on Europe has a long way to go.
