Double Olympic gold medallist Mo Farah has pulled out of the Birmingham Grand Prix today.
He was due to race in the 1500 metres at the Alexander Stadium this afternoon. Yesterday he appeared before the media saying his reputation was being ruined after doping allegations against his coach Alberto Salazar.
The double Olympic gold medallist told a press conference he has not seen "any clear evidence" that Salazar had been involved in doping.
"I'm a clean athlete, against drugs and anyone who isn't should be banned for life.
"I want to know the answers and the easiest thing to do would be to jump.
"But if you can't show me proof (Salazar), I'm out. I will be talking to people because it's my reputation"
Olympic champion Mo Farah has pulled out of today's 1500m race at the Diamond League event in Birmingham saying he is "emotionally and physically drained".
"This week has been very stressful and taken a lot out of me. I have not been able to focus properly on today's race," Farah said in a statement.
"I want to run well in the IAAF World Athletics Championships in Beijing and have decided it is better for me to go back to the US, seek answers to my questions and get back into training."
"I apologise to the people who bought tickets to come and watch me race and ask for your understanding at this time."

“Even my mum who’s not particularly into athletics was really proud and it’s a really standalone thing to captain my country."
"I’m quite nervous about giving a speech, but I take inspiration from some of the ones I’ve been a part of. It takes a lot to stand up in front of peers like that and it’s quite a personal thing_.”
