Comedian and TV presenter Patrick Kielty has taken to Twitter to make an impassioned argument against Boris Johnson's Brexit plan.
The Co Down man took issue with the Tory MP's latest article in the Telegraph headlined 'My plan for a better Brexit'.
He tweeted: "Dear Boris Johnson, there is no better Brexit when it comes to the Good Friday Agreement and Northern Ireland. As you still seem bamboozled by all this Paddywackery, here's a few pointers for your next stab in the dark.
"1. Northern Ireland is made up of a majority of Unionists (as in the Conservative and Unionist Party) and, believe it or not, a rather large minority of Nationalists (as in Irish Nationalists).
"2. These Irish Nationalists don't see themselves as British but rather inconveniently as Irish (who knew?).
"3. For over 30 years we killed each other because of these differences which means Northern Ireland is nothing like Camden or Westminster.
"4. The Good Friday Agreement ended that violence by the following devious magic - Unionists were guaranteed that Northern Ireland would be part of the UK until the majority voted otherwise.
"The Irish border was removed and the island linked so Nationalists could pretend they were already living in a United Ireland (yes, Tony Blair did sleight of hand much better than you).
"5. Some of these Nationalists then accepted being part of the UK as their day to day lives were essentially Irish.
"6. This cunning plan was sold to us on the basis that we were all part of the EU therefore fixation on nationality was so last World War.
"7. Implementing the Good Friday Agreement was torturous (think Brexit with actual bombs, not metaphorical suicide vests) but we finally made peace. Yet 20 years later NI remains a divided society.
"8. Thanks to your glorious Brexit vision NI will become more divided as some form of economic border checks will become part of daily lives.
"9. If those checks take place between NI and Ireland, the Nationalists who were once happy being part of the UK will change their mind.
"10. If they take place in the Irish Sea some Unionists will be livid. However they'll still support being part of the UK."
Mr Kielty went on to outline 10 more pointers in which he said "Brexit lies" had opened a Pandora's box for Northern Ireland and meant a border poll was now inevitable and could easily be lost by unionists.
"By the time the penny drops that you can't preserve the Union you want without the one you don't, it will be too late," he continued. "You will be remembered not as the Churchillian visionary you delude yourself to be but the ignoramus who triggered the break-up of the UK. If there's any justice all this will come to pass when you're Prime Minister so you can finally swim in the constitutional sewage you've created.
"Meantime, if you're so concerned about keeping Northern Ireland totally aligned with the rest of the UK where's your support for our same sex marriage and women's right to choose?"
