GB duo Ohuruogu and Idowu off form ahead of Worlds

Ohuruogu suffers last place shock in London

Britain's top medal hopes suffered a disappointing day in their final major event before the World Championships in South Korea.

Olympic 400m champion Christine Ohuruogu finished last in her event in 51.87 seconds at the London Grand Prix.
And triple jump world champion Phillips Idowu placed third with a best effort of 17.07m.
"I don't know what happened, to be honest - I felt really good, and I warmed up OK," Ohuruogu said.
"I had a cold last week but it's gone now. I'm very shocked.
"My coach [Lloyd Cowan] is going to tell me that that was rubbish, and he'll be right."
Idowu also disappointed in the triple jump, finishing behind 21-year-old American Christian Taylor and Nigeria's former Briton Tosin Oke.
