UK Athletics has found no evidence of wrongdoing by Mo Farah in the initial findings of its investigation into allegations of doping against his coach, Alberto Salazar.

UKA launched a review following allegations in a BBC Panorama programme shown in June that Salazar, the head coach at the Nike Oregon Project in Portland, where Farah trains, had violated several anti-doping rules. Salazar, who is an "unpaid consultant" for UKA, has strenuously denied all the accusations.

Farah, who was not accused of any wrongdoing in the BBC documentary, has vowed to stick by his coach unless any allegations are proven.

Farah is preparing to defend his 5,000m and 10,000m titles in Rio.

The initial findings will come as a welcome boost for the 32-year-old, whose performances on the track, amid a tumultuous summer off it, have been impressive.
