The EU Constitution's troubled journey towards ratification has created a higher quality of debate on the role of the EU then I can recall in a long time. We can be thankful for that if not for the content of the constitution itself!
I've had various thoughts forming on this matter, how rapid EU expansion and the race to the bottom in social and environmental protections are connected. But I hadn't quite honed my ideas into a coherent whole when along pops the now ex-MP Richard Allan with an exquisite post on his blog explaining matters just as I would have done. Hurrah.
