Jules Bianchi: Tributes to F1 driver after death aged 25

Former world champion Jenson Button has led tributes to "real fighter" Jules Bianchi after the Frenchman died as a result of severe head injuries in a crash at the 2014 Japanese Grand Prix. The 25-year-old had been in a coma since crashing his Marussia car into a recovery vehicle nine months ago. McLaren driver Button tweeted on Saturday: "Last night we lost a truly great guy and a real fighter #RIPJules. "My sincerest condolences to his family and friends." Ex-Marussia driver Max Chilton, 24, raced as team-mate to Bianchi for two years in F1. They also competed in karting from the age of 10 before rising through the racing ranks together.
