In Britain where Brexit currently means Brexit, and for the moment little else, in Northern Ireland the issue continues to open up old wounds.
Concerns about a hard border are forcing conversations about issues, which while had not been settled, had at least found some unspoken accommodation between the two EU members and parties of the Good Friday Agreement.
But the Brexit debate and the UK’s eventual withdrawal from the EU has forced these issues front and centre with uncomfortable questions now being asked.
The issue of Lough Foyle territorial ownership, which has 25km of coastline in Donegal, came into sharp focus after a parliamentary question raised by British Labour MP David Anderson, the Shadow Secretary of State for Northern Ireland, last week.
The recently appointed Conservative Secretary of State for the North, James Brokenshire, gave the following reply: “The Government’s position remains that the whole of Lough Foyle is within the UK.”
In response, the Irish government was quick to firmly disagree with Brokenshire’s claim with the Department of Foreign Affairs remarking: ”Ireland has never accepted the UK’s claim”.

The issue of territory around Lough Foyle has been a matter of dispute between Dublin and London ever since the island of Ireland was partitioned in 1922.
