Is the UK too London centric?

As the capital of England, you would expect London to be the powerhouse for business attracting many diverse industries. However, I do believe that it has gone a little too far, and London is becoming overcrowded with businesses and people. There are many great cities in the UK open for business and cities which are very well connected to the capital too. It just seems that no-one wants to give these other cities a real good chance. Birmingham, Leeds and Manchester are three vibrant and thriving cities which are home to many industries and walks of life. However, it's not enough to draw the big guys out of the capital. London is too crammed with high rise flats and is seeing an ever expanding area in the South East of England. More and more people flock to London for work rather than being drawn to these other magnificent cities. The UK is far too London centric and more needs to be done to bring other major cities into the limelight.
