The best athletes on the planet – including British star Dina Asher-Smith – make their eagerly anticipated return to the London Stadium in front of a huge crowd.Asher-Smith, who won the 200m world title in 2019, is searching for top form ahead of next month's World Championships in Budapest and faces formidable opposition in Stratford, with Jamaican Shericka Jackson and the USA's Sha'Carri Richardson also set to compete.In addition to Asher-Smith, home fans will also be roaring on Olympic and world silver medallist Keely Hodgkinson in the 800m and Eilish McColgan in the 5000m. The latter will – fitness permitting – go head-to-head with double Olympic champion Sifan Hassan, who won April's London Marathon on her most recent visit to the capital.
