In the run-up to the UK’s 2016 Brexit referendum, the Irish border barely featured in the debate. Two years on, the question of how to keep the 310-mile (500-kilometer) frontier free of checkpoints and patrols threatens to derail Britain’s plans for an orderly departure from the European Union. How did we get here? And what happens next?
Tell me about Ireland’s border
Long controlled by Britain, Ireland was split in 1922 into the Catholic-dominated south and the mainly Protestant north. The south won independence, the north remained under British rule. For decades, customs officers patrolled the new border to stop smugglers. Later, soldiers manned heavily fortified checkpoints and watchtowers on the border, as violence raged across the region.
Today, the frontier is pretty much invisible. Violence largely ended with a 1998 peace deal, and the fact Ireland and the UK were both members of Europe’s single market meant there was little need for checkpoints. Visitors often only realize they’ve crossed into the north when they encounter the Union Jack flag flying or curbstones painted red, white and blue.
So, what’s Brexit got to do with all this?
Now the north and south of Ireland are a little bit akin to two adjoining US states. Think of Ohio and Pennsylvania. When the UK leaves the EU, that relationship will becomes something closer to that between the US and Canada. So, notionally, checkpoints, patrols and cameras need to return after Brexit.
What’s the problem with that?
The absence of border controls are a powerful symbol of the region’s peace process, which ended violence between nationalists fighting for a united Ireland and loyalists defending Northern Ireland’s place in the UK. A return to checkpoints and cameras risks stirring up old hatreds, as well as presenting obvious targets for new attacks.
Business will suffer too
The island of Ireland in many respects works as one integrated economy, with supply chains criss-crossing the border. Take Guinness, the most iconic of Irish exports. Diageo brews the stout in Dublin, loads it into ‘silver bullet’ tanker trucks and ferries the beer 90 miles north to Belfast. There, it’s bottled and canned before being ferried back south. While the whole operation today is seamless, a hard border could cause delays of between 30 minutes and an hour for each truck crossing.
So, what’s the solution?
Both sides have agreed that no new border must emerge on the island after Brexit. But the UK also wants to avoid a border between Northern Ireland and mainland Britain. Some kind of border has got to go somewhere as the UK is leaving the single market that makes the current setup permissible.
The EU has a plan — and it’s called the “backstop.” What that means is that if all else fails, Northern Ireland would keep most of the bloc’s rules after Brexit so that no border needs to go up. So, for example, food standards in the region would match those in Ireland, even if the British government opted to slash standards elsewhere in the UK.
Is that it?
No. The EU doesn’t want Northern Ireland used as a back door for sub-standard goods to slip into the single market. After Brexit, UK markets may be opened up to food like chlorine-treated chicken and genetically modified crops, which are banned in the EU. So checks will be needed at British ports to ensure such products aren’t shipped to Northern Ireland, and then transported south and into the single market. The British have reacted furiously to that.
Why are the British so angry?
The UK says the EU effectively wants to annex Northern Ireland, with some even muttering that the Irish government is seeking to unify the island by stealth. And even if UK Prime Minister Theresa May liked the plan, her political weakness complicates matters. She’s propped up in power by the DUP, a Northern Irish party which views Belfast as quintessentially British as London. It’s threatening to veto any deal which sets up barriers with the mainland.
So are we heading for a no-deal Brexit?
The EU won’t start sign off on the divorce deal unless the border riddle is solved. So, there is a possibility the UK could crash out of the bloc without a deal. In practice, that could mean tariffs on goods traded between the EU and the UK, vast lines at ports, grounded airplanes and maybe even food and medicine shortages in Britain.
Sounds fairly apocalyptic
Yes, and that’s one of the reasons it probably won’t happen. Both sides are edging towards a compromise, and most expect a deal between the EU and UK government.
It’s worth remembering that more than possibly anybody else, the Irish want to avoid the UK crashing out. Without a deal, border controls would likely return between the north and south, while the vast trade that runs east-west between Ireland and Britain would be devastated by tariffs and delays.
Ah, no need to worry so?
Hold on. While May wants an agreement, she faces a massive challenge getting virtually any deal through Parliament. She doesn’t have a majority at Westminster, and wherever she turns, there’s opposition. Her hope is that enough lawmakers peer into the abyss, contemplate the chaos no deal could bring and back her plan.
Final question; is this all leading to a united Ireland?
Hours after the Brexit referendum, Martin McGuinness, the former Irish Republican Army leader turned politician, said it had bolstered the case for a plebiscite on a united Ireland. But for that to happen, Britain must judge it likely that Northern Ireland would opt for reunification. Despite polls showing support inching up, demand is not yet overwhelming. There’s also little appetite in London or Dublin for a vote both sides fear could jeopardize the region’s fragile peace.
