What is Levi Roots' birth name, as revealed in connection with Dragon's Den?

Levi Roots' birth name is Keith Valentine Graham.

Roots is the stage and professional name of the British-Jamaican musician, chef and entrepreneur who became widely known after pitching Reggae Reggae Sauce on Dragon's Den. His sauce brand helped connect Caribbean food with a mass British retail audience.

He was born in Clarendon, Jamaica, and moved to the United Kingdom as a child. Before his food-business success, he had a career in music and performed reggae. The name Levi Roots became closely associated with both his public persona and his food company.

His Dragon's Den appearance is often treated as the beginning of his fame, but he was already an established musician. The programme instead marked the point at which his entrepreneurial work reached a much larger national audience.
