Police Reform and Social Responsibility Bill

I note that the policing Minister's letter says that he hopes to make savings and not to use the £600 million. Today's Birmingham Mail points out that despite an earlier promise that the Pope's visit would be subject to a special grant for security, that grant was never provided, and west midlands police have virtually exhausted their contingency for special events. If that happens around the country, how can the Government possibly hope to make savings on the Olympics?
