Millions of people tuned in to witness the historic moment the 45th president of the United States was sworn in.
But those watching the ceremony on the BBC noted on social media that the channel appeared to be using subtitles from Tracey Beaker spin-off ‘The Dumping Ground’.
The BBC appeared to make the mistake during Trump's swearing-in.
Text reading “Oh whatever” and “mum will get into trouble” appeared on screen with Mr Trump’s face, and as the camera switched to Barack Obama, read: “Just shut it, yeah? Oi! Leave him alone!”
Twitter user Kaytality uploaded the footage showing the bizarre error.
She said: “BBC News have the wrong subtitles on and it’s pretty glorious.”
The subtitles were erroneously displayed while Barack Obama and Donald Trump listened to a prayer.
During the swearing-in ceremony, the subtitles read: “No one wants you here.
“You’re only in a mood because mo’s gone.
“Just shut it, yeah? Oi! Leave him alone! Just tell him to get out of my face!”
The subtitles were from popular children's television show 'The Dumping Ground'.
The BBC are reportedly investigating the mistake.
