Olympic champion Christine Ohuruogu and Shana Cox both secured their place in London by finishing first and second respectively in the 400m at the athletics Olympic Trials, but things were far less clear in the women's 800m.
Marilyn Okoro and Emma Jackson had the 'A' standard but finished fifth and seventh in the final, with Okoro paying for a foolish early pace. Scotland's Lynsey Sharp was a surprise winner ahead of Jemma Simpson, but both will need to run the qualifying time by July 1 to claim their place in the team.
Greg Rutherford sealed his place in London by winning the long jump, but there was bad news for world junior champion Jodie Williams, who left the track in tears after pulling up with an apparent hamstring injury 15m from the line in the women's 100m final.
