City of Westminster Bill [Lords]

Like my hon. Friend the Member for Wellingborough (Mr Bone), I am greatly encouraged by what the Minister has had to say. If the Government introduce their own legislation on this issue, will it trump the private legislation that local authorities wish to pass; or if the local authorities pass these Bills and they end up being more authoritarian than the Government's proposals, will those measures still stand? It is important to clarify that point before we decide whether these Bills are worth reviving.
