European Union (Amendment) Bill

I think that the United Kingdom negotiated a good deal. Indeed, many in France would say that the rejection of the constitutional treaty in a referendum has led to a worse deal for France on the Lisbon treaty. If the right hon. Gentleman had his way, and there were a referendum and it were lost, what evidence does he have that the UK could renegotiate a better treaty for itself? In that case, would he wish to return to the status quo ante, with, as he believes, the EU functioning not very well?
