During his time at now defunct low-cost airline Go, David Magliano says he learnt a lesson that has guided him through his career. “My CEO Barbara Cassani, who was an inspiration to me in so many ways, always said ‘do what you say you’ll do’. That non-negotiable rule of following through on commitments has served me well,” he says. Today, Magliano’s goal is to implement a membership strategy for The Guardian that will double reader contribution over three years and reduce its reliance on advertising, something he cites as his biggest upcoming challenge.  He says: “If we can, it will go a long way to securing the future of independent, liberal journalism, which is essential for a healthy society.” Tasks of this magnitude are not foreign to Magliano considering he spearheaded – and won – the bid for London to host the 2012 Olympic Games.
