London Local Authorities Bill [Lords]

I am extremely interested to hear the Toowoomba and Braintree examples. Does my hon. Friend know whether the authorities in London have explored the idea of copying any of those examples before resorting to legislation? Is he aware of any pilot studies that have been carried out and evaluated which led them to the conclusion that the only way to solve this potential problem, which they perceive as a problem, is to encourage more regulation and legislation?
