Member state of the European Union

There are a number of countries with strong links with the EU, similar to elements of membership. Following Norway's decision not to join the EU, it remained one of the members of the European Economic Area which also includes Iceland and Liechtenstein (all former members have joined the EU, and Switzerland rejected membership). The EEA links these countries into the EU's market, extending the four freedoms to these states. In return, they pay a membership fee and have to adopt most areas of EU law (which they do not have direct impact in shaping). The democratic repercussions of this have been described as ``fax democracy'' (waiting for new laws to be faxed in from Brussels rather than being involved in drafting them).
