Gabby Logan presents coverage of the London Anniversary Games from the Olympic Stadium in East London.

Staged to mark the one-year anniversary of the London 2012 Olympic Games, the event sees Usain Bolt make his return to London.

Six-time Olympic champion Bolt is one of 28 Olympic medallists scheduled to compete in the two-day event in the capital with GB's own gold medallists Jessica Ennis-Hill and Mo Farah also in action.

The event doubles up as the London Grand Prix, the 11th round of the 2013 Diamond League competition which sees the world's best athletes clash across the globe throughout the summer.
