"The material is extremely timely and the book can be a reference point to all scholars, politicians and students, who are interested in shaping the constitutional future of these islands."

"This is an impressive book that is highly original empirically, covering new ground on party development and change in relation to the EU. It is novel theoretically in challenging the idea that traditional cleavages based on socio-economic, religious, or centre-periphery faultlines can explain the approaches of the parties towards Europe. Instead, multi-level historical institutionalism, based largely upon the variety of political institutions in which those parties sit (and interact with others) offers a more fruitful exploration of party behaviour."
