Ireland needs to act now to stop huge UK barriers arising from Brexit
Even if the UK stays in the EU customs union, there are huge risks that new invisible barriers will be created to trade across the Border in Ireland, and between Ireland and Britain. Ireland must use every legal means available to prevent this damage, including making full use of all the institutions set up in the Good Friday Agreement.
Things could go seriously wrong if we are not very careful.
For example, if, after Brexit, the UK develops different standards for packaging, plant safety, pharmaceutical safety, or food safety, the disruption to cross-border trade in Ireland, and to trade between Ireland and Britain, could be immense.
