A row involving some of Russia\'s biggest film stars tarnished a glitzy awards ceremony after the presenter accused an actress of making an election video for Vladimir Putin to protect her charitable fund. The dispute took place at the prestigious annual Nika awards hosted by the Russian Academy of Cinema Arts, broadcast on state television late Sunday and seen as Russia\'s equivalent to the US Oscars. The row erupted as an award was given to Chulpan Khamatova, one of Russia\'s best-loved actresses who leads a respected charity and controversially made a video endorsing Putin\'s successful March 4 presidential election bid. The host of the ceremony -- the opposition-inclined television host Ksenia Sobchak -- stunned the audience by openly asking Khamatova if she would have made the pro-Putin video if she had not had to worry about her charity. Khamatova\'s endorsement of the Russian strongman had unsettled some of her fans who saw the softly-spoken star as an unlikely cheerleader for Putin. \"Chulpan -- you know how I bow before your talent and your human generosity and kindness,\" said Sobchak. \"It is because of this that here and now I want to ask you this. If you had not been involved in charitable work would you have supported Putin as a candidate or would you have stayed away from political activity?\" Her intervention prompted furious whistles from the audience and other actors to leap to the defence of Khamatova, whose charity is regarded with universal admiration in Russia for helping treat children with cancer. \"Why are you doing this?\" fellow star actor Yevgeny Mironov, who was also on the stage after presenting an award, told Sobchak. \"It\'s just a question. I admire you very much,\" an uncomfortable-looking Sobchak told Khamatova, who did not answer the question and said the ceremony was aimed at recognising artistic achievement. Even the Kremlin\'s chief economic adviser Arkady Dvorkovich later waded into the scandal to attack Sobchak, accusing her on Twitter of \"hooliganism\". Putin\'s campaign team had wheeled out a succession of celebrities including Khamatova and conductor Valery Gergiev to take part in short campaign videos called \"Why I am voting for Vladimir Putin\". But despite the controversial nature of the incident, state-controlled Channel One television made no attempt to edit it out of their recorded broadcast. With the furore showing no sign of dying down, Sobchak strongly defended her actions on her blog, saying she had asked a question that \"worried both me personally and I think many other people.\" \"The reaction to the question stunned me,\" she said. Some bloggers hailed Sobchak for boldly asking a seemingly taboo question but even some liberal voices questioned her decision to so publicly interrogate an actress seen by many as a national treasure. \"It was low, vulgar and unpleasant,\" wrote Alina Grebneva of the liberal Moscow Echo radio station. Other commentators suggested it was Mironov who provoked the whole affair by saying in his introductory remarks that Khamatova had to put up with the \"do-nothings, the bastards who sit on the couch and criticise you.\" \"It was Mironov who turned the ceremony into a venue for polemics and he got his riposte,\" the vice president of the Russian media association MediaSoyuz, Elena Zelinskaya, told the RIA Novosti news agency.
