Lewis lives between his terrace house in Newham and the family home in Milton Keynes, which he shares with his wife, Pamela, 49, a former Hackney primary school teacher, and their three daughters, Nadine, 21, Naomi, 18, and Chloe, 16. Like many of the boys at his academy, he knows what it is to grow up without a father and in poverty. His parents split up shortly after arriving in the UK from Guyana and the family struggled to survive on his mother's meagre earnings. At his secondary school, Lewis was regularly excluded for violent and disruptive behaviour.
