The United Kingdom's push to renegotiate its status in the European Union threatens the European project. In the past, the bloc granted special concessions to the British, such as allowing them to keep the pound sterling during Maastricht Treaty negotiations. These concessions inspired other EU members to ask for similar treatment -- most notably Denmark, which also managed to opt out of the euro. However, this is the first time that London has openly demanded the return to a previous stage in the process of European integration. At no other time has a country tried to dissociate itself from the bloc in this way. The decision not only challenges the Franco-German view of the European Union but also makes a compromise extremely difficult and risky between France and Germany and the United Kingdom.
