Police Reform and Social Responsibility Bill

I understand that the ministry has met the council leader, but in his letter he says that the Government’s proposal will not work. He says that it will not fulfil the objectives set by the Government. I cannot imagine what has happened in the conversation with committees and officers of the council meeting to come to that conclusion. What happens if the Bill is enacted as the noble Baroness would want and it turns out as time passes that Westminster City Council is right and the Government are wrong?
