I suspect the quickest way for Scotland, Wales or NI to break away from the UK would be to give England a vote on the matter however I think we're perhaps getting a little off topic here.

Can you link to any of these opinion polls? I'm not having a go, I just can't find any.

Also, how are you so certain the rest of the UK doesn't want us? You know the North/South links with Scotland alone go a lot further than tribal football support, right?

There is significant support in Great Britain for Ireland to reunify as a political entity. A poll conducted by ICM for the The Guardian in 2001 revealed that 26% of Britons supported Northern Ireland remaining a part of the UK, while 41% supported a united Ireland.[6] The British Social Attitudes Survey in 2007 found 32.25% supported Northern Ireland remaining part of the UK, and 40.16% supported Irish reunification.[7] The poll has been run 19 times between 1983 and 2007, with each result being in favour of Irish unity. The highest support came in 1994 with 59.36% of the respondents supporting Irish reunification, while 24.09% supported Northern Ireland remaining in the UK.
