The EU also consisting of democracies should not cause confusions. Conider the first and third largest democracies, India and the USA: both consist of states that hold their own elections. The same way Britain is a democracy while having other levels of democracy, that is regional elections in Scotland and Wales and North Ireland and local elections, too. The UK is also interesting because democracy comes in combination with undemocratic elements -- e.g. the Queen, the Lords, and temporary statutory rule in North Ireland.
