The UK Eurovision entry, SuRie, was interrupted by a stage invader shouting "Nazis of the UK media" as he snatched the microphone during the UK's Eurovision performance.
The intruder, who was dressed in a black and red bandana and slogan t-shirt, rushed the stage as SuRie was performing her track Storm, shouting "we demand freedom" before he was hauled off by security.
The incident left SuRie without a microphone for at least ten seconds and she was forced to clap along as cameras cut to fans in the audience.
She later resumed her song and finished to rapturous applause.

Graham Norton who is hosting the BBC's commentary said: "There was a stage invasion, SuRie coped incredibly well, I can't stress enough what a brilliant job she did, she must have been terrified".
The European Broadcasting Union has offered SuRie the chance to perform again but she chosen not to. Norton told viewers: "She decided she didn't want to perform again.
"Who can blame her? She has absolutely nothing to prove. She coped beyond admirably.
"How vulnerable would you feel on stage all by yourself?"
