Dafne Schippers retains 200m crown at IAAF World Championships

Dutch sprinter Dafne Schippers held on to retain her world 200m title on Friday as the United States had another night to savour in London and two experienced campaigners claimed more gold. Schippers, who won bronze in the 100m, roared off the bend into the final straight and looked as if she would coast safely home. (Video courtesy: Perform)
