STORY: Ivan Zhdanov, a close ally of Putin's pre-eminent domestic critic, spoke in an interview in Kyiv. He said he had come to Ukraine to see for himself the impact of Moscow's invasion and to be able to report a true picture back to Russians.
"Putin is a common enemy for us, and we have already been fighting against him for many years," Zhdanov, head of Navalny's embattled Anti-Corruption Foundation, told Reuters on a central square in the Ukrainian capital.
He said Navalny's team were interested in striking up a dialog with the Ukrainian government.
Navalny, already serving a jail term of two and half years, received a new nine-year sentence in March for fraud and contempt of court. He said last week he had been charged in a new criminal case and could face up to 15 more years in prison.
