IAAF special congress passes president Coe's reforms

Jamaica's sprint superstar Usain Bolt, however, has thrawn his weight behind Coe, saying that "Seb Coe is trying to make track and field more transparent to everyone so they can see what shape it is in and to make sure there is not one person fully in control."

"That's a bold move from him as IAAF president," said the 30-year-old while receiving a record sixth IAAF Athlete of the Year Award at Friday evening's year-ending gala.

"That's also helped the sport to make people more confident and to trust the sport more," added Bolt, a nine-time Olympic champion who's retiring after the 2017 season.

"I am incredibly proud of the decision that was taken this morning, both the endorsement for the work of the Council by the Congress and let me immediately place on record my thanks to the reform team," said Coe at a post-meeting press conference on Saturday.

"We now have structures, we now have frameworks and foundations that will create a safety net. That safety net has to also be responsive to cultural shifts and cultural changes. But it is a good day and there is now a whole heap more work to do to make sure that we drive on into a far better future," he added.

A new version of report by Canadian professor Richard McLaren is expected to come public on Dec. 9, which may reveal more about the organisation and doping in Russia.
