Russian opposition leader Alexey Navalny has demanded that Moscow should return his clothes, claiming that Western laboratories had found traces of a Novichok nerve agent in and on his body.
Navalny, who is recovering in Berlin's Charite clinic, fell violently ill during a flight from Siberia to Moscow on August 20. He spent two days in hospital in Russia before being airlifted to Germany.
"Before they allowed for me to be taken to Germany, they took off all my clothes and sent me completely naked," Navalny wrote on his website in his first blog post since emerging from a coma.
"Considering Novichok was found on my body, and that infection through contact is very likely, my clothes are a very important piece of evidence," he said.
"I demand that my clothes be carefully packed in a plastic bag and returned to me."
Navalny's clothes were taken by investigators and are no longer in the hospital in Siberia's Omsk, where he was initially hospitalized.
