Viewers were confused by what appeared to be a technical error on Good Morning Britain – when the show zoomed in on Carol Vorderman’s chest.

The 57-year-old star, who was wearing a stripy, polo neck-style top, was a guest on the ITV show, hosted by Susanna Reid and Piers Morgan.

Later, Vorderman spoke about postponing her solo flight around the world to spend time with her mother, who was battling cancer and died last year.

“I am going to do it in the next two or three years. I think when I’m 60, in three years,” she said. “That’s when I’m probably going to do it.”
