Thanks Jim, an interesting link.

As you say, it shows a 2/3 majority for a united Ireland (at present). That's clear enough.
Apart from a brief comment about the number of people in 'the North' who wish to remain in the EC, it doesn't clarify what this 'United Ireland' would be.
Would the Republic join Northern Ireland as part of the UK, or would Northern Ireland become part of the Republic and therefore part of the EC?

The closest the article comes to quoting the question doesn't seem to address this point:
Asked how they would vote if a referendum was held tomorrow, 65% of the sample electorate said they would vote in favour of a united Ireland.

Cheers
