Local Government Finance Bill

I certainly was not here when the previous Administration were in government, but I would like to give the Minister another opportunity to answer the question put to him by my hon. Friend the Member for Warrington North (Helen Jones) from the Front Bench about what exactly a local authority would be doing differently under these proposals from what they are doing now. If this is about planning policy, what evidence does he have to suggest that granting permissions for extra commercial floor space results in an increased business growth take?
