For the past several weeks, we've been asking for your nominations for the 2006 News of the World Children's Champions awards - in recognition of those who have made a significant contribution to improving the lives of children around the country. The winners have now been chosen, and all this week, we'll be profiling the people who have made a difference. We begin with Juliet Tanti, an M.E. sufferer who risked her own life diving into a raging river to save a 7-year-old child. Something inside her, she says, told her she had to do it.
