25 years since the people of both Northern Ireland and the Republic voted to accept the Good Friday Agreement, another potential referendum looms on the distant horizon. That Agreement, though primarily to end the violence of the Troubles, allows for a future border poll that would determine whether Northern Ireland remained part of the United Kingdom, or re-joined the south. But crucially, few people realise that it\u2019s not just up to Northern Ireland voters: consent is required on both sides of the border. And for voters in the Republic, it\u2019s more complicated than you might think.

Andrea Catherwood investigates what the new, highly-educated, liberal, European-focused Irish Republic thinks about the possibility of its northern neighbours, from whom they were parted more than 100 years ago, re-joining their country. Polls suggest a number of issues; symbols, violence, economics. Can Ireland afford it, and does it want to? Is it just too much trouble?

With contributions from the main Irish political parties, as well as economist David McWilliams and Irish Times political editor Pat Leahy, the assumption of a yes vote from the republic isn\u2019t as straightforward as many assume.
