The new constuencies have been announced following the boundary review. These have produced a very different political map. We will do some number crunching later, to work out how this will affect the likely political affiliation of each of them and give a bit of commentary, but as I'm sure you are interested here are the constituency by ward.
One small example is rail services. Many Mill Hill residents are users of Thameslink. At present as part of Hendon our MP has three stations in his catchment area on the same rail line. He therefore has a strong incentive to lobby for good services on this line. Under the new arrangement, Mill Hill will be represented by an MP with far more interest in the Barnet Branch of the Northern line. The Mill Hill Thameslink service will be a small sideshow. It seems to me that new boundaries have simply been drawn as post colonial borders in Asia and Africa were, with no regards for the local demographics or interests. Splitting Mill Hill from the Hale will massively disenfranchise voters in both parts of NW7, as their interests will become very low down the list of MP priorities in the new world.
This is being repeated all over London and I suspect I'm not the only one to see problems arising.
