Coverage from the second day of the London Grand Prix, the 12th Diamond League meeting of the year.

As always, a top-class field will travel to Crystal Palace for the event.

Highlights include the women's 400m, where there is a fascinating duel between American duo Sanya Richards-Ross and Allyson Felix, world champions over 400m and 200m respectively. The men's 400m race will also be one to watch, while home hopes will be pinned on Great Britain's Jenny Meadows, who claimed 800m bronze at last year's World Championships in Berlin.
