Poland’s men’s 4x400m squad had to withdraw following a positive outbreak, while Belgian sprinter Eline Berings criticised the testing procedure after being forced to withdraw from the semi-finals of the 60m, claiming it was due to a false positive.
Britain’s Amy-Eloise Markovc, 25, won the 3,000m and team-mate Keely Hodgkinson, 19, struck gold in the 800m.
