Highlights - Simpson leads GB success in London (UK user only)
Jemma Simpson led home a British one-two-three in the women's 800m at the London Grand Prix on Friday in a repeat of the result at the UK Championships.
The 25-year-old kicked off the bend to lead home Jenny Meadows and Marilyn Okoro in two minutes 01.08 seconds.
"The 800m at the World Championships in Berlin is wide open and I wouldn't put it past one of us to win a medal," Simpson told BBC Sport.
Mo Farah won the 5,000m but Phillips Idowu was third in the triple jump.
Idowu, who won Olympic silver, endured a mixed evening with three fouls at Crystal Palace, but he closed with a leap of 17.16m to finish behind America's Brandon Roulhac, who jumped a career-best 17.33m.
Britain's Larry Achike's produced a season's best 17.07m to boost his chances of securing a spot on the plane to Berlin.
Farah's hopes of breaking the 27-year-old British 5,000m record, held by David Moorcroft, were hit by the blustery conditions in south London, but he produced a superb turn of speed in the home straight to outsprint Kenya's Sammy Mutahi and win in 13:09.14.
"I just wanted to win and I'm really happy with it," said Farah. "It wasn't easy in the wind, but the crowd made a big difference, they gave me a boost coming off the final bend."
In the men's 800m Canada's Gary Reed led from the front to cross the line in 1:45.85, with Britain's Michael Rimmer fading in the final yards to finish fourth.
"In the last 30m, I tightened up a bit," he said. "I'm not used to having bodies around me when I'm finishing, but I'm getting better with every race."
Kate Dennison broke the British pole vault record for the eighth time, clearing 4.58m at the third time of asking to finish fifth. The event was won by Poland's Anna Rogowska, who cleared 4.68m, to beat Russia's Yelena Isinbayeva, who was last defeated in a major event in 2003, on countback.
Britain's Nicola Sanders hung on to win the 400m in 51.56 seconds from the fast-finishing American pair Shana Cox and Monica Hargrove.
"The wind down the home straight was pretty fierce," Sanders told BBC Sport.
"It's nice to get a good win for the confidence and the time will come."
Bahamas sprinter Debbie Ferguson-McKenzie won the women's 200m in 23.11 seconds with Britain's Emily Freeman storming down the back straight to clinch third in 23.34, just behind America's Marshevet Hooker.
Cuba's Dayron Robles suffered a slight scare in the 110m hurdles, but he came through in 13.29 seconds, out-dipping Ryan Brathwaite of Barbados. Britain's Andy Turner was third in 13.66.
America's Christian Cantwell won the men's shot put with a throw of 21.82m, despite having a shot dropped on his foot during the warm-up.
