Britain's double Olympic champion Mo Farah has said he will continue to work with coach Alberto Salazar who is being investigated by the U.S. Anti-Doping Agency (USADA).
The 32-year-old Farah has been under the spotlight since the American was accused of violating anti-doping rules in a BBC documentary earlier this month.
The BBC programme Panorama, in association with American website ProPublica, made a series of allegations including that Salazar had given Olympic 10,000 metres silver medallist Galen Rupp the banned anabolic steroid testosterone.
Salazar, who issued a lengthy and detailed denial of the allegations on Wednesday, has worked with Farah since 2011 and operated as a consultant for British Athletics since 2013.
"Following all the speculation I want to make it clear where I stand," said Farah who was not accused of any wrongdoing in the BBC documentary.
"Although it's been a difficult time I asked Alberto to respond to the allegations made against him and he has now done so in full," added the Briton in a statement on his Facebook page.
"As someone I've worked with for many years I feel I have to believe in Alberto and the evidence he has provided.
"Based on that evidence I will continue to work with him and hope now that I can focus on what I do best, training hard to win medals for my country. Thanks."
Farah is due to return to competition at the Monaco Diamond League meeting on July 17.
