World indoor champions Molly Caudery and Georgia Hunter Bell triumphed in the pole vault and 1500m at the Diamond League meeting in Rome.

The 24-year-old was unable to challenge in the unfamiliar distance, finishing in 51.14 seconds, while compatriot Amber Anning finished in fifth in 50.19.
In the women’s 200m, Amy Hunt and Dina Asher-Smith took fourth and fifth respectively with times of 22.52 and 22.76 seconds, in a race won by Olympic champion Julien Alfred from world title-holder Melissa Jefferson-Wooden.
