We have a similar thing on this side of the Atlantic where people argue about whether it is acceptable to refer to the United Kingdom of Great Britain and Northern Ireland as "Britain". I feel it is, as an abbreviation, and it is my preferred abbreviation, along with "GB", because I like to look forward to the time when we won't have a monarchy any more and I therefore don't like the abbreviation "UK", and also, despite not having any strong Irish connections, I tend to feel that Ireland ought to be reunited. This may seem like the opposite of my opinion on the US/America question, where I prefer "US", and I suppose it is, but I have my reasons!
