i predict scotland will leave the uk and apply for membership of the eu, if they do, this will be good for rep of ire, as they can still export beef and farm products to scotland, which will then be geographicaly the closest european country, the uk will be pleased to get rid of northern ireland which is a drain on their economy, if northern ireland leaves the uk and joins europe, the uk will consist of wales and england without northern ireland the uk will be better off economically, the most likely scenario is that they may refuse to join the rest of ireland but apply for membership of the eu, as a seperate entity.
