"Through a unique dataset covering half a century of policy-making in Britain, this book traces how topics like the economy, international affairs, and crime have changed in their importance to government. The data concerns key venues of decision-making - the Queen's Speech, laws and budgets - which are compared to the media and public opinion. These trends are conveyed through accessible figures backed up by a series of examples of important policies.
