Experts from the Voluntary Anti-Doping Association (VADA) have arrived in Ukraine at the invitation of Ukrainian boxer Wladimir Klitschko.
The expert delegation is led by VADA President Margaret Goodman, the Sportarena online edition reported.
The experts came to carry out a health check-up for two leading presidential candidates, incumbent President Petro Poroshenko and showman Volodymyr Zelensky, if they give their consent.
As UNIAN reported earlier, Zelensky on April 3 declared his readiness to come to the debate with Poroshenko ahead of the April 21 runoff, however, he voiced a number of conditions. In particular, he said the debates should be held at Kyiv's Olimpiyskiy Stadium with all TV channels being able to air the event live, while both candidates must undergo medical tests to prove there are "no alcohol or drug addicts" among them.
Poroshenko agreed to hold the debate with Zelensky at the stadium.
On April 4, speaker of Poroshenko's election headquarters, Oleh Medvedev, said that Poroshenko had invited Zelensky at the Olimpiyskiy health center to pass the relevant tests.
In turn, Zelensky's headquarters rejected the idea of having his blood tested at the health center and announced he would do this at a private laboratory.
On April 5, Zelensky had blood tests at a private clinic, Eurolab. Poroshenko in turn had relevant tests at the Olimpiyskiy health center.
Wladimir Klitschko called the presidential candidates' medical tests ridiculous and offered to arrange new drug testing at VADA.
