Police and Justice Bill

My hon. Friend is making a powerful point. Is he aware of any evidence that is adduced to sustain the argument that that 4,000 is some sort of magic figure? The Leicestershire force, with 2,000 officers covering 1 million people, is being absorbed into one with 9,000 officers covering 4.5 million people, but that will create serious risks, especially in relation to localised policing. Is he aware of any such academic or other professional evidence?
