Rusada's suspension was imposed in November 2015 and lifted by Wada in September 2018

Australian Olympic champion Jared Tallent has become the second high profile athlete to endorse a shake-up of the World Anti-Doping Agency.

It comes after Wada reinstated Russia's anti-doping agency following a three-year ban for alleged state-sponsored doping.

Four-time Olympic medallist Tallent said: "Wada's governance, in its current form, is not fit for purpose."

His comments follow those made by British Paralympic medallist Ali Jawad.

Powerlifter Jawad, a silver medallist at Rio in 2016 and a member of UK Anti-Doping's Athlete Commission, had called for a "far-reaching reform" of Wada.

And race-walking champion Tallent, 34, backed the proposals put forward by Jawad in a paper, 'The Alternative: Reforming Wada's governance for a new anti-doping age'.

Wada president Sir Craig Reedie said Russia's reinstatement was "subject to strict conditions" and that the anti-doping authority must be given access to former Moscow laboratory data and samples.

Tallent described the governance structure of Wada as being "broken" and said "athletes were worried about the direction" the organisation was heading in.

"In the absence of there being the robust and single-minded leadership that we require, it is now incumbent on us, the athletes, to drive the change that we all want to see in Wada," he said.

"The lack of independence, along with the fact that decisions that impact the livelihoods of clean athletes are made surreptitiously and 'behind closed doors', are two areas of huge concern to international athletes."

In a lengthy statement, Tallent also condemned Wada and the International Olympic Committee for their response to bullying allegations and called for a "transparent inquiry" into the matter.

Two-time Olympic gold medallist Ed Moses says he was told to "shut up" at a World Anti-Doping Agency meeting.

While Beckie Scott, Wada's Athlete Committee chair, has previously told the BBC that some officials tried to "bully" her over her opposition to Russian reinstatement.
