• Sprinter is first Briton to win three world championship medals• GB men and women teams each take second place in 4x100mDina Asher-Smith put one last dollop of icing on her stunning week in Doha by winning another silver medal in the 4x100m relay – and become the first
British athlete ever to win three world athletics championship medals.
Asher-Smith, who glided to gold and silver in the 200m and 100m earlier in the week, ran a storming second leg as Britain’s women took silver behind Jamaica.
