UK Athletics has found no impropriety on the part of Mo Farah after receiving the initial findings of a review into the double Olympic champion’s relationship with coach Alberto Salazar.

The review followed a BBC documentary last month that alleged Salazar and US Olympic silver medallist Galen Rupp had violated anti-doping rules.

UK Athletics said in a statement that it had received this week the initial findings of the review by its Performance Oversight Group (POG).

It said the findings would have to be shared with Britain’s anti-doping agency before any wider circulation, and did not expect any public announcement until after the world championships in Beijing next month.

“However, with reference to the first and most vital objective of the review, the board can confirm that none of the extensive information supplied to the POG contained any evidence of impropriety on the part of Mo Farah,” it said.

Nor did the information give “UK Athletics any reason to question the appropriateness of the input given by the Oregon Project to Mo Farah‘s training regime”.
