GB News guests clashed over the Union Jack flag after the British Eurovision entrant called it 'divisive' and 'nationalistic'.
Olly Alexander sparked controversy after saying he is “ambivalent” about the red, white and blue flag.
The Years and Years singer, who will perform dance song Dizzy in the competition, said he wants to reclaim the Union Jack “in a positive way”.
During a debate on GB News, Cheryl Baker – who won the Eurovision Song Contest in 1981 as part of pop group Bucks Fizz – insisted she was “proud” of the flag.
But comedian James Barr defended Alexander, saying he is right when he says young people should “take back” the flag.
Baker said: “To represent Great Britain in a competition like the Eurovision Song Contest, the biggest annual competition in the world, you must be extremely proud of it and I'm sure I am. I'm thrilled to have been involved.”
Barr responded: “When you look at the Union Jack, all you have to do is look at the kinds of networks that drape themselves in the Union Jack flag and you [GB News] are one of them.”
Host Patrick Christys interrupted: “It doesn't stop you from getting paid by us for this evening, so if you have that problem with it, you can leave.”
An irritated Baker then said: “It's our flag, for God's sake, every country has a flag.”
Referring to tonight's semi-final, she continued: “Look tonight, the flags of every country are flying, everyone is proud to support their own flag, why should we be any different? Why aren't we proud to support our own flag waving?” own flag? I know I am.”
Barr responded: “What Olly said is true, he said he is ambivalent about it and wants to redefine what our flag means.
“He's wearing a Union Jack bikini, that's what he means by it. He wants to take back our flag for young people.”
But Baker responded: “That doesn't make sense. That's nonsense, what does that mean?”
The comedian said: “The only time the Union Jack flag is great is when the Spice Girls wear it, when Olly Alexander wears it as a bikini or when it has been changed to pride colours.
“That flag represents our country in many different ways and Olly is right: it is important that we take it back.”
