Comedy duo Ant and Dec caused a stir by claiming that Northern Ireland is not part of Great Britain.

No matter what your political or nationalist stance is: it can’t be denied that Northern Ireland is a part of the United Kingdom. However, the hosts are correct: it is not technically considered a part of Great Britain.

We're ready! Hurry up and get here! #SaturdayNightTakeaway

A post shared by Ant & Dec (@antanddecofficial) on

On last night’s episode of their long-running TV show “Saturday Night Takeaway”, Ant (Anthony McPartlin) and Dec (Declan Donnelly) made the contentious statement while introducing their returning game segment, Sofa Watch.

As Ant explains that Sofa Watch is coming back with the new title Sofa Watch Battle of Britain, Dec interjected, “Can I just stop you there for a second. I’ve just been thinking, what about Northern Ireland?"

“See Northern Ireland is not actually a part of Britain but we still want it to be part of Sofa Watch,” Dec continued.

In retaliation, Ant showed new graphics which displayed Sofa Watch Battle of Britain, before a purposefully delayed “and Northern Ireland” flashed across the screen.

Viewers of the award-winning show, which has been on air for over 15 years, were not happy with the OBE-ordained comedians.

However, many were quick to school the Twitter universe on basic facts of geography. Northern Ireland is technically NOT in Great Britain (made up of Scotland, England, and Wales).

Laughing at this whole Northern Ireland/Great Britain crap on Ant & Dec. May not be included as Great Britain but its 100% part of the UNITED KINGDOM & 0% "the North of Ireland" would love to know who taught some people basic geography. #AntAndDecsSaturdayNightTakeaway

#SaturdayNightTakeaway Ant & Dec are factually correct, Great Britain comprises of Scotland, England and Wales. Channel Islands, Isle of Man & Northern Ireland & Gibraltar are not part of that unit. They comprise the United Kingdom with GB.

Some of "ra peepl" really are stupid. Can't believe the uproar with ant & dec now on banned list. Northern Ireland is part of the uk. It isn't part of Great Britain. They've obviously never checked their passports or watched the Olympics

Geography is hard for some people. Northern Ireland is not part of Great Britain!!

Alas, the Great Britain/Northern Ireland issue wasn't the only hiccup on last night's show.

When an audience member named Louise was selected to compete in the Win the Ads segment, she dropped the F-bomb live on air as the cameras rolled to her.

#SaturdayNightTakeaway When you Win the Ads. 🤭🤣🤣🤣 F-Ing Hell.

A red-faced Ant then made the woman apologize for her bad language.

"Now I have to apologise for any bad language somebody may have mouthed when they were surprised earlier," he chided. "Say sorry, Louise."
