Should Britain join the Euro?

I used to be strongly in favour of a single European currency, and my partner is from the continent, but after living over there for 3 years, I've completely revised my opinion.

Culturally, Europe is much more socialist and controlling, when compared with the historic British attitude of an island nation based on international trade and financial freedoms, as evidenced by our reputation as one of the best places to conduct international business, and our base as the world's leading financial centre.

Using the old dictum that "he who controls the currency controls the nation", by giving up the national currency, you are also giving up much of the control and handing it to another power, with vested interests of its own.

Fortunately, at this point in time, most Britons realise this and are opposed to the single currency. We all know this, so why even bother going to the expense and hassle of a referendum?
