We have always known that London benefits hugely simply by being London, but the above figures, for transport infrastructure, take the biscuit. The figures might be the extremes, but in general London still benefits twice as much as the regions.
I wonder in how many other areas of infrastructure London gets to use the lion's share of the country's funds, due to the London centric thinking of MPs, bushiness and the media? I will bet that there are a few.
There is a lot of anger in the "London versus the rest" way the country is run and any political party willing to stand up and say that it will change things, dramatically, will get a good polls boost.
