RTE caused a storm after showing a map of the island of Ireland with Northern Ireland cut out.
The map was shown on the massively popular Late Late Show on Friday night during a segment about poverty and health in the Republic.
Introducing the segment, host Ryan Tubirdy said: “Where you live in Ireland will decide when you die.”
The map was created by obesity expert Dr Eva Orsmond using Irish census data for a new documentary.
It was colour coded to show areas according to how poor or affluent they are and how that could affect your health, but the area of Northern Ireland had been removed.
This caused fury among viewers who took to social media to slam the broadcaster for only showing 26 counties.
Sinn Fein’s deputy leader Mary Lou McDonald tweeted yesterday morning: “What is this all about? Who took it upon themselves to mutilate the map of Ireland. And why?”
U105 presenter Frank Mitchell sent a picture of Northern Ireland to RTE’s account saying: “Here’s the other bit of the jigsaw. They may have lost the lid of the box!”
Former Lord Mayor of Belfast and sitting Irish senator Niall O Donnghaile tweeted: “Who in the production crew on RTE Late Late Show thought this was a good idea and wouldn’t cause offence? #Unacceptable.”
"Republic of Ireland world view ! Thank you RTE!" tweeted MP Ian Paisley.
In a statement, RTE said: "This segment of The Late Late Show related to the upcoming documentary Ireland's Health Divide, which includes new research data, based on the 2016 census. As such the map shown on The Late Late Show reflected the counties covered by the 2016 census.“
