I've looked up the proposed changes for my area. Essex is all Conservative, so they'll be losing a seat or two. What strikes me about my new constituency is that it cuts across all sorts of district boundaries and will lose the sense of being a local constituency. It's a very strange shape and will be difficult for the MP to know it all.
One of the arguments against PR has been that people would no longer have a 'local' MP, because the constituencies would be bigger with a number of representatives. That argument has now been undermined, but I'm still not holding my breath that we'll have PR any time soon.
