Mo Farah: Doping allegations are 'killing me, killing my family'

“To be labelled something you are not and labelled a cheat is not fair: prove I am a cheat or leave me alone."

Double Olympic champion Mo Farah has insisted he is “100 per cent clean” but admitted he would sever all ties with Alberto Salazar if doping allegations against the coach were proven.

Farah, who won both the 5,000m and 10,000m at the London Olympics, insists it is not fair he is being accused by association but believes Salazar is entitled to be treated as innocent until found otherwise.
