Lawrence Okolie: From McDonalds to Matchroom

As Lawrence Okolie prepares to fight for a cruiserweight world title, Eleanor Roper hears his story. Overweight and bullied at school, Lawrence's life changed when he found boxing. The sport has taken him from Hackney, London to the Rio Olympics. On March 20, he'll fight Krzysztof Głowacki for the vacant WBO world cruiserweight title. Unbeaten in his 15 professional fights, this is his biggest challenge to date.
