The 51-year-old author of the Noughts & Crosses teenage book series vowed to use her two-year tenure to “bang the drum” for diversity, saying it was vital for young people to learn about different cultures.
“Children will go with any story as long as its good but white adults sometimes think that if a black child’s on the cover it is perhaps not for them,” she said.
“Books teach children to see the world through the eyes of others and empathise with others. It’s about the story.”
Blackman, a London-born author whose parents came to Britain from Barbados, said there was a distinct lack of black and Asian children in picture books.
She said that when she was younger, she never once read a book that featured a black child, which left her feeling “totally invisible”.
