Moscow: Stark divisions within Russia's elite were exposed yesterday when a hot mic mishap showed Prime Minister Dmitry Medvedev slamming security forces as "jerks" for launching an early morning raid against a filmmaker. Medvedev on Friday gave an extensive end-of-year interview to five Russian channels in a clear bid to keep up his profile after ceding the Kremlin to his mentor Vladimir Putin earlier this year. But attention has focused less on the interview than on a six minute video posted on the Internet of Medvedev's supposedly off-the-record conversation with journalists that came afterwards. In a relaxed exchange, Medvedev is shown bantering on topics ranging from wristwatches to whether Santa Claus exists. But most notably he also launches a blistering attack on the habits of the Russian security forces.
