The Privy Council Office provides advice on communications matters, which would include advertising matters, as to whether it complies with the government direction that was set out, and also whether that will align with what other departments are doing. So, for instance, I talked about Ebola and other public health concerns. You want to make sure that the right hand knows what the left hand is doing when government goes out to communicate so that citizens have the best possible advice and support from their government.
