Mo Farah has won the 10,000m gold medal at the 2015 World Championships in Beijing.
Farah, 32, recorded a final lap of 54.15 to pull away from Kenyan challengers Geoffrey Kamworor and Paul Tanui to seal his sixth successive global distance.
Farah's preparations for the world championships have been undermined by allegations of doping surrounding his coach Alberto Salazar and running partner Galen Rupp, claims strenuously denied by the duo.
But the Londoner marked his return to the grand stage with a trademark surge to the front just before the bell, crossing the finishing line with a time of 27 minutes and 01.13 seconds.
Despite early control from Kamworor, Tanui and fellow Kenyan Bedan Muchiri, Farah prevailed with help of Galen, with the American settling for a fifth place finish with a time of 27 minutes and 08.91 seconds.
The double Olympic champion's attention will now turn to winning the 5,000m gold. Should he do so, he will become the first man to complete a 5,000 and 10,000m double at consecutive World Championships.
