It's not just the communication strategy I'm afraid. Sometimes it seems to me as Britons quite like playing the odd one out (and enjoy the right to a critical look on the others) as well as the feeling of safety for not being dissolved in the half-billion voice cacophony.
Continental Europe must understand this.
France's 'exception' is another name for the same, in a way.

Take for instance the issue of the sterling. The french franc wasn't wept for too much, nor was the deutsche mark, while the sterling is a mark of britishness even more than London's bobbies, big ben or doubledeckers.
