Miles De Souza was a fictional character on the ITV soap opera Emmerdale. He made his first appearance on 1 November 2007 and his last appearance on 31 July 2008, and was portrayed by Ayden Callaghan.
Miles is the son of Donald De Souza. Although he is the only son of a millionaire, Miles has not always been close to his father. Likeable and able, he struggles with feelings of worthlessness which only feed on his personal issues, including alcoholism and depression.
When Nicola returned to Emmerdale she told people that her husband was dead. It was eventually discovered by journalist Jasmine Thomas that her husband Donald was in fact alive and on a life support machine.
Jasmine also found that Miles was an alcoholic and would only benefit from his father's will if he stopped drinking. Nicola was trying to seek out Miles and catch him drinking, before cutting off Donald's life support. But Jasmine became determined to find Miles first and get him on the wagon. She tracked him down in a hostel, but he was still drinking and was caught in the act by Nicola and David Metcalfe. Yet despite Nicola's belief that she could let Donald die and be free to inherit the business, Jasmine took Miles to see his father, while offering him a place to stay.
