What does Scotland mean for other independence bids?

"The concept of the unitary state is going to become much more difficult except for a very small country," Stephen Tindale, associate fellow at the Center for European Reform, an independent think tank, said from London. "It does augur increased pressure on central governments to change the (political) relationship" with regions...

...What appears certain, however is the inevitability of more economic blocs across the world and an accompanying increase in the cultural diversity of nations. And that will require the consideration of different political relationships. One solution, argues Tindale, of the Center for European Reform, is to adopt a model of federalism used by Germany or the United States, with clearly delineated authority embedded in constitutions, with substantial powers for states or regions.
