Gabby Logan introduces live coverage of world-class athletics from the Queen Elizabeth Olympic Park in London. This is the only Diamond League meeting to be held over two days, and more than two dozen Olympic or world champions are among the stars fine-tuning their preparations for next month's World Championships.

British Olympic champions Jessica Ennis-Hill and Greg Rutherford are both due to compete on this second day and rekindle the magic of 'Super Saturday' at London 2012, when they and Mo Farah each won gold within 45 minutes of one another. British athletics' newest superstar, heptathlete Katarina Johnson-Thompson, will line up in the long jump, while Kenyan David Rudisha returns to the scene of his incredible world-record 800m run in the Olympic final.
