what is the pros and Cons of Britan joining with Euro currency?

Answer 1

Queen Elizabeth does not have a sour face. She's an old woman who has suffered many trials in her life and is still working at 80.
I think Britain should join the EU completely. It might rescue them from US domination.
Accepting the Euro would make it more convenient for tourists and facilitate trade with other European countries.
A strong EU might be able to stand up the the US.

Answer 2

For the English people, the problem will be that they will not be different than the rest of Europe in this aspect any more.
For the rest of us, the problem will be that we will end up with coins with Elizabeth's sour face on them.
