The European Union might not be the only union facing a break up over Brexit.
Political parties in Northern Ireland and Scotland, which both voted to Remain in the EU, are seizing on the political paralysis in Westminster to push their independent agendas.
For Ireland its led by political party Sinn Fein.
The party leader Mary Lou McDonald told CNN’s Christiane Amanpour that Brexit is an opportunity to unite Northern Ireland with the Republic.
“A referendum on Irish unity will be absolutely essential”, she says, if the UK leaves the EU without a deal.
“We have a situation where the North of Ireland take a democratic decision, they reject Brexit, and yet, due to the sovereignty of Westminster, Brexit can be imposed.”
And, it’s a similar story in Scotland.
Calls are growing here once again for a second referendum - not just on Brexit, but on their membership of the UK as well.
First Minister Nicola Sturgeon says the case “the case for Scotland becoming an independent country has never been stronger.”
19-year-old student Abbie Archibald was too young to vote in any of the previous votes, but now she has come of age.
Given the chance she’d vote to Remain in the EU, but she doesn’t think it would be democratic to do a do-over on Brexit.
It's a different story however when it comes to the possibility of another vote on Scottish independence -- she would vote to leave the UK.
“The circumstances are completely different,” she says.
“We’re now potentially not going to be a part of the EU, and Scotland could have the chance to thrive as its own country.”
The threat of Brexit was a decisive factor in the Scottish independence referendum, says Angus MacKenzie, a Building Surveyor and part-time piper.
In the last vote for Scottish independence he voted to stay in the UK. Now, if there is a hard Brexit, he would vote to leave.
“All the arguments that were against independence, are the arguments for it now. It’s twisted round”, he tells me.
“One major argument was keeping our currency, but now the euro looks set to outperform the British pound. Another argument was wanting to stay in the EU, but now that has gone.”
For those Scots who want to remain in the UK, the effect Brexit is having on the independence argument is alarming.
Bob Gilchrist wanted to stay in the EU, but that Brexit disappointment aside, he still wants to remain in the UK.
“There’s so much division and conflict now, who knows what people are going to vote for,” he says.
“In some ways your heart says it be nice to be independent, because we get dragged into a lot of this UK discussions without wanting to, but to me, the idea of Scotland being independent, particularly economically, is just a bit of a nonsense.”
Meanwhile, for many -- like Fiona Vine who works at the prestigious University of Edinburgh, political fatigue is weighing heavily on many minds.
She says that while calls within the SNP may be growing for another Scottish Independence vote, it might not spread beyond, given the current state of upheaval.
“I’m not sure if there is appetite for that to happen again I think people are weary of politics.”
