For children with backgrounds of poverty, neglect and abuse, the City can seem an incomprehensible and daunting place. Commerzbank's head of treasuries, Can Biritrim, however, is keen to show them it can be a source of support. Working with the charity Kids Company, which supports London children who have severe behavioural, emotional and social difficulties as a result of childhood trauma or neglect, Biritrim, together with head of prop trading Tim Fisher, invited three of the children the charity works with to the London office for the day.
