Germany’s government handed transcripts of interviews with Alexei Navalny to Russia, as part of the Kremlin’s probe into the poisoning of the activist, a Justice Ministry spokesman said on Saturday.

The ministry has demanded a thorough probe into Navalny’s poisoning and made the interrogation protocols available to Russia’s government. The Kremlin now has all the information needed to carry out a criminal investigation into the poisoning in August — including blood, clothing and tissue samples — the spokesman said.
