My brother Malcolm Ball, who has died aged 61 of cancer, made a lasting contribution to the lives of young people in south-east London through his youth work in Lewisham.
In 2003 he co-founded, with his colleague Denis Hunter, the innovative Lewisham Young Mayor Project, encouraging young people in the borough to engage in local politics. Each year a young mayor is elected, and the chosen person has an annual budget to work with and a cabinet of volunteer advisers to implement the manifesto.
