Almost 2,000 athletes at the World Championships will be blood-tested in an unprecedented anti-doping programme.

Mark Lewis-Francis will not take part in the 100m at the World Championships later this month after being overlooked by UK Athletics.

Jamaica’s Usain Bolt comfortably wins the 200m whilst Kenya’s Vivian Cheruiyot sets a world-leading time in the 5,000m in the Stockholm Diamond League meeting.
