Benjamin Zephaniah: “All the books have to change. The way we educate has to change.”

After leaving school at 13, he went from wanted criminal to best-loved poet, refusing an OBE, fighting institutional racism and working with Nelson Mandela. Now a university professor (and part-time Peaky Blinder), Benjamin Zephaniah is turning 60, publishing his autobiography and going on tour – and he’s as political and radical as ever.
