That unprincipled wretch Nick Clegg, who would gladly prostitute the UK to Brussels, is bleating that this will isolate the UK from Europe. That's not really a bad thing IMO...
Not isolate Britain from Europe, just the European Union. More will follow ... Finland is very reluctant (with the True Finns rising to power), in Sweden 88% are against the Euro, Denmark will most likely have a referendum (binding for the parliament) with an average of 65% against the EU and rising, Poland will have to pay
about 30% of their GDP to save the Euro (i.e zero chance of reelecting if passed), a majority of Dutch parties want a referendum (though probably not binding), Hungary will give problems ... and some countries is or will be so bankrupt that they'll have to leave the Euro-zone. Bye-bye EUSSR.
Britain will probably save a lot of money, if your politicians keep their back straight and don't fold:
