Abstract: | When the Liberal Democrats joined the Coalition government in May 2010, there was an expectation that they would have a restraining effect on the Conservatives, particularly in the area of European politics. But after almost five years as the junior party in the Coalition, the Liberal Democrats struggle to demonstrate their influence over the government's approach to Europe. Not only did they let the Conservatives lead the Coalition's European agenda, but they will be forever associated with the government that brought the UK closer to the exit door of the European Union. The article argues that this outcome is the result of a series of avoidable if surprising mistakes, such as the choice of ministerial portfolios and the party's attitude to the Coalition's monitoring mechanisms, as well as some unavoidable mistakes that could have not been foreseen when the Coalition was formed. |
