As the Conservatives and Liberal Democrats pass their first 100 days in government, John Kampfner goes in search of the perfect coaltion.
As the coalition reaches its first 100 days in government, John Kampfner looks at how coalitions really work. What are the limits of what they can do - and what are the unintended consequences? John travels to Derby to meet local councillors who've had to work together in recent years - and finds out if there are lessons that can be learned by the new government.
John will also get advice from unexpected quarters on how coalitions can stick together -- and how they're perceived by the public.
