Peter and Daniel Field
Peter Field, 60, is a technical engineering manager of a small international firm based in Italy. The father of two is firmly anti-euro. He was a member of the now defunct Referendum Party - set up to campaign for a referendum on the euro.
He says: "The euro should not replace the pound. There are a whole host of reasons - there are virtually no benefits whatsoever to joining. We would lose an awful lot of economic control to Europe.
"There is no such thing as a currency without a country. If you believe there is, then you are also agreeing to a Federal Europe. I am against that on sovereignty grounds.
Mr Field fears his business would suffer if the euro were introduced. He says: "It would mean initially very little, but as time went on and the government lost all control of interest rates and control over our economy and taxes, then we would begin to suffer.
"You only have to look at southern Ireland where economically they are taking off in an uncontrollable fashion which will have a knock-on effect on inflation. I do not believe that Britain will get left behind. We are one of the leading economies of the world. If we refuse to go in, that will not change - in fact we will become even more powerful.
"We are still going to be trading partners with Europe - we are not going to pull out of Europe." Mr Field says that although he and Daniel disagree, they don't argue over the issue."The young are idealistic - Daniel's beliefs don't surprise me."
Mr Field says it is highly unlikely he will change his mind over the euro. He explains: "There are lots of papers and documents supporting why we should not go into the euro but very little concrete evidence supporting the other side of the argument." He believes the conservative party best represents Britain's interest - he said: "I think they've got it about right."
Daniel, 26, a trainee accountant, earns £20,000 a year. He takes a completely opposite view to his father. He says: "Just having a single currency makes it much easier for business and trade. There would be no fluctuations in interest rates and it would be better for the manufacturing industry. It would mean one huge market place which would be bigger than America or Japan."
Labour-voter Daniel added: "I'm proud to be British. But I can separate loss of sovereignty with the the economic benefits. I think it would do a lot of good for people's prospects. The problem is that a lot of people go back to the war - they can't separate the currency issue from this. The older generation just mix this up.
"I think we need to talk about it more - the whole thing has simply not been explained properly." He adds: "I respect my dad's views, but I am certainly more liberal than he is about this."
