The International Association of Athletics Federations said progress has been made with Russia's anti-doping procedures but there are still 'issues' and therefore a suspension will remain in place.

Russia's head of athletics Dmitry Shlyakhtin is travelling to London this week to address the sport's governing body in a bid to have his country's international ban lifted.

Shlyakhtin will make a speech at the IAAF congress on Thursday, a day before the World Championships Begin at the London Stadium.

Rusaf has been banned since November 2015 after an independent world anti-doping agency inquiry exposed state-sponsored doping on a massive scale.

Both the IAAF and international Paralympic committee still regard Russia as non-compliant.
