Cameron Wishes Euro Bloc Well as U.K. Negotiates Isolation - Businessweek
Prime Minister David Cameron said Britain refused to sacrifice sovereignty to save the euro, remaining outside an agreement by European nations to tighten budget rules.
Cameron broke ranks with French President Nicolas Sarkozy and German Chancellor Angela Merkel after he failed to secure safeguards that would have stopped European Union plans to police financial services in London, Europe’s trading hub. The U.K and possibly Hungary, Sweden and the Czech Republic will remain outside the new rules.
From what I understand of this, Cameron has basically refused to negotiate with Europe over a propsed Financial Transactions Tax on the basis that it would lead to an exit of funds from "The City". Sovereignty certainly is an issue in Europe; especially when it comes to taxation policy because I'm not so sure that moving towards a more uniform taxation code in Europe is even feasible given how all the various countries economies are driven.
These sorts of arguments when on with the European Coal and Steel Community with only just 6 countries; with 27+ and with more than just coal and steel to worry about, it'd be a nightmare.
