Menkov won gold at his home World Championships in Moscow in 2013 with a personal best and national record of 8.56 metres.

He also claimed victory at the 2013 European Indoor Championships in Gothenburg after taking silver at the previous year's World Indoor Championships in Istanbul.

The 26-year-old should now be able to compete under the IAAF banner at next month's World Championships in London.

"The IAAF Doping Review Board has agreed that the applications of 16 Russian athletes have met the exceptional eligibility criteria to compete in international competition as neutral athletes under competition Rule 22.1A(b) while the Russian national federation (RusAF) remains suspended," a statement declared.

Others cleared to compete neutrally include Ilya Shkurenev, a multi-eventer who finished fourth in the decathlon at the 2015 World Championships after winning the European indoor heptathlon title earlier in the same season.

Two home gold medal winners at the 2013 Summer Universiade in Kazan have also been cleared in shot putter Alexsadr Lesnoi and 1,500m champion Valentin Smirnov.

Irina Gordeeva, a high jumper who finished third at the 2012 European Championships, is also cleared along with 2014 European bronze medal winning triple jumper Alexey Fedorov.

Others granted permission to compete are discus throwers Viktor Butenko and Iuliia Maltseva, 400m hurdler Timofey Chalyy, hammer thrower Danil Danilov, triple jumpers Irina Gemeniuk and Viktoriia Prokopenko, sprinters Alena Maminia and Viacheslav Kolesnichenko and shot putter Konstantin Lyadusov.

Race walker Olga Eliseeva is also cleared purely to race at the European Under-20 Championships taking place in Grosseto, Italy, from July 20 to 23.

"The participation of all these athletes as neutral athletes in international competition is still subject to formalities for eligibility under IAAF Rules being completed and subject to acceptance of their entries by individual meeting organisers," the IAAF added.

The Russian Athletics Federation (RusAF) remains banned from international athletics competitions due to doping allegations, pending its completion of reinstatement criteria.

Athletes are permitted to compete neutrally if they can demonstrate they have been operating in an "effective testing system". 

Thirty-nine applications have now been approved out of over 150 attempts.

"It is important to reiterate that this review process is about ensuring there is a level playing field in which the world’s clean athletes have confidence," said IAAF President Sebastian Coe.

"I want to thank once again the members of the Doping Review Board for their continued dedication and diligence in assessing these applications to compete internationally as independent neutral athletes. 

"It’s a huge task and one which cannot be rushed if we are to ensure the rights and aspirations of clean athletes are protected."

A further nine Russian athletes were declared eligible last week to compete at the IAAF World Under-18 Championships scheduled to be held in Nairobi from July 12 to 16.

Another 13 have also been cleared to compete at senior level, including two reigning world champions, 110m hurdler Sergey Shubenkov and high jumper Maria Kuchina. 

Long jumper Darya Klishina and 800m runner turned whistleblower Yuliya Stepanova were each cleared to compete internationally last year.
