We joined Europe , lets join the Euro , it has worked well for the participating 15 or so countries and has stopped banks ripping people off especially so in the UK where the spread - difference between buying and selling - is more than 10 % . The Euro has now been firmly established as the currency of Europe and in many respects stronger and more stable than the US $ .
In the UK the main obstacle is not the financial implications but the mentality that says we should retain our pound regardless , we do not want to surrender our sovereignty ??? We surrendered our sovereignty to the rest of the world years ago , for crying out loud we do not have any more sovereignty to surrender.
The UK will be the last to join the EURO , if indeed it ever does , people can not see how easier it would be for both business , which already transact with their European partners in Euros , and for travellers who will save all those charges levied by the greedy banks. But is part of the English heritage and people are reluctant to see the pound disappear.
