Party politics in a powerless Parliament.

Have party politics, as they developed over the twentieth century, any useful role to play within a Parliament neutered by the EU following implementation of the Lisbon Treaty and its forerunners? The question seems particularly pertinent today following the Dispatches programme broadcast on Channel 4 last evening. I will be blogging in more detail on this in the coming days. In the iterim perhaps readers would like to consider the following question - Are individual MPs and Peers more corrupt than the Parties to which they belong and which were the first to become thus so thoroughly corrupted, the individuals or their Parties?
