"The essence of the message was that the Government wanted to ensure a degree of consistency in message on key messages and therefore wanted to clear key messages through the Prime Minister’s office."
Shades of Yes, Minister in the above. What a giggle.
Just blog it, agencies. Bypass the Bureaucracy, Subvert the Hierarchy Comrades!
