Although a "golliwog" is a character found in 19th century children's literature inspired by a black-faced rag doll, the term is widely interpreted as racist.
A BBC spokesperson said there was a discussion about the Australian Open in the 'green room', and Carol referred one of the black tennis players (supposedly Jo-Wilfried Tsonga) as a golliwog.
Well, Carol should have targeted Andy Murray during his bad hair days instead.
