The Scot will look to build on his showing in Friday’s Diamond League meeting in Monaco, where he finished a close second to Kenya’s Emmanuel Wanyonyi as the Olympic and world 800m champion broke the long-standing men’s 1,000m world record on his debut at the rarely run distance.

Wanyonyi joins Wightman in London, along with Olympic silver medallist Marco Arop of Canada, Olympic finalist Bryce Hoppel of the United States, plus Ireland’s Mark English and English duo Max Burgin and Ben Pattison.

Olympic champion Keely Hodgkinson leads a strong English contingent in the women’s 800m along with world silver medallist Georgia Hunter Bell, in a race that will also feature the Netherlands’ Femke Broeders-Bol, who has stepped up in distance from the 400m hurdles – in which she has won multiple Olympic and world medals.

Julien Alfred heads to London after a blistering run in Monaco, where the Saint Lucian clocked the third-fastest women’s 200m time in history, a world lead and personal best.

The double Olympic medallist will defend her London title against a world-class field including American Gabby Thomas and English trio Dina Asher-Smith, Amy Hunt and new British champion Success Eduan.
