DMITRY MEDVEDEV has been long on talk and short on action ever since he became Russia’s president in 2008. That is why some were surprised on September 28th when he dramatically fired Yuri Luzhkov, the mayor of Moscow since 1992, citing a “loss of confidence”. The 74-year-old Mr Luzhkov was one of Russia’s most powerful politicians and a senior figure in the ruling United Russia party. He is a household name all over the country; his wife, Yelena Baturina, a construction magnate, is Russia’s richest woman.
