BBC Breakfast viewers were left baffled after an oblivious reporter was caught on air in a live blunder.
Ben Boulos, 39 and Nina Warhurst, 42, hosted Sunday's edition of the BBC programme.
Towards the end of the show, the duo interviewed a group of farmers who had taken on an unusual challenge to raise money for mental health charities.
However, as Ben and Nina chatted to the men, the camera suddenly cut away from the interview and an unsuspecting reporter appeared on screen.
The female journalist seemed unaware that she was on live TV as she prepared for a news report and sorted through some papers.
The camera then came back to Nina and Ben, who wrapped up their interview with the farmers - also seemingly in the dark about the technical blunder.

Nina was heard saying to Ben: "It's a really important cause which is a lovely thing to do - you didn't know I was bilingual, did you?"
Ben replied: "I didn't, you learn something new every day."
Nina added: "That's it for Breakfast for now, we'll be back tomorrow as ever from six, enjoy your day."
BBC Breakfast viewers clearly did notice, with one writing: "Feel bad for the unknowing reporter we’ve just watched get ready for the news #BBCBreakfast."
