UK Athletics says it has found "no evidence of impropriety on the part of Mo Farah" as it investigates doping allegations against his coach.

The organisation has conducted its initial findings into Alberto Salazar.

Farah was questioned by the US Anti-Doping Agency in a hotel in London last Saturday for five hours.

But the double Olympic champion, who missed two drug tests in the lead up to London 2012 according to The Daily Mail, has never been suspected of any wrongdoing.
