The BBC World Service has rebuffed a Russian state request to remove an interview with a Russian artist and activist who called for a march to win more autonomy for Siberia.
Artem Loskutov spoke to the BBC Russian Service on 31 July, and the website bbcrussian.com reported the interview.
A BBC spokesperson said the story was fully compliant with BBC guidelines.
In a complaint to the BBC the Russian state media watchdog Roskomnadzor warned it might block bbcrussian.com.
Russian campaigners in support of the march have had their pages blocked on Vkontakte, the most popular social network in Russia, often likened to Facebook.
Loskutov spoke in Russian on the BBC's current affairs programme BBSeva. He told the interviewer Seva Novgorodtsev about a planned "march for the federalisation of Siberia" in the city of Novosibirsk.
In a separate blog piece, Loskutov described the march as "part parody, part provocation, but also, partly, a real attempt to gain autonomy".
