Davies denial – Nick Davies stepped aside from his role as IAAF Deputy General Secretary on Tuesday, saying his action would enable the IAAF's Ethics Board to be able to review his case properly. His relinquishing of his position, which could be temporary if he is proven innocent, comes after publication of a leaked email he sent in 2013 about doping in Russia. Davies denies having formulated a secret plan to delay the naming of Russian athletes who had tested positive for doping.
Family Affair – Davies' 2013 email was sent to Papa Massata Diack, who was then the IAAF's Marketing Consultant. The Senegalese is son of Lamine Diack (pictured here on the right), who governed the IAAF from 1999 to 2015 before handing over the reins of power to incumbent Sebastian Coe in August.
Eye of the Storm – Papa Diack is accused of extorting money from Russian athlete Liliya Shobukhova to conceal a drugs test she had failed. Diack, who has been charged by the IAAF's Ethics Commission, denies any wrongdoing.
World Standing – The 2013 World Athletics Championships was the biggest sports event Russia had held since Moscow staged the Summer Olympic Games in 1980.
Outside View – The knock-on effects from Russia's doping scandal has given the IAAF unprecedented problems as it battles to protect its credibility. The body was founded in 1912 and has been headquartered in Monaco since 1993.
