Cumbrian,

Surely your not suggesting that the House of Commons is playing a central role in shaping public policy on EU affairs or the constitutional structure?

Rather, isn't Parliament the last place that these and other important topics are debated and policies regarding which refined? Aren't the Parties (with the possible exception of the SNP) incapable of demanding and productively contributing to public debate on these core issues?

Is this the mark of vibrant democratic institutions in action?
