Diederick Santer, Executive Producer of EastEnders: E20, commented: "Not content with having E20 written by new writers, and our theme tune remixed by the audience, we've now found four talented newcomers from London to front the show. Emer, Bunmi, Ricky and Sam are brilliant young performers, noisy and fun."

Leon, played by Sam Attwater, is sexy and effortlessly cool but with a short fuse and a lack of respect for those in authority. Leon's mum died when he was young and he takes a great deal of responsibility for his alcoholic father. He is a dedicated boxer and takes pride in the fact that in the ring "no one touches the face".
Sam remarked: "It is a great privilege to be working with such great actors and on such an established show. It's an amazing opportunity and I'm really enjoying tackling a character like Leon who has so much going on!"
