Public Confidence in the Media and Police

I am grateful to the Prime Minister for giving way. Returning to the issue of the police's operational independence, he rightly emphasised the important principle that politicians cannot tell the police whom to investigate and what to pursue, but that cuts both ways. What message does he think the Mayor of London was sending out when he said, in the same weeks when John Yates was scoping his inquiry, and just days after John Yates sent his e-mail to the Prime Minister's chief of staff, that any inquiry and any allegations were codswallop, politically motivated and not worthy of discussion?
