Moscow: A prominent Russian cartoonist won loud applause at a usually politics-free awards ceremony when he suggested President Vladimir Putin shared responsibility for the death of a jailed anti-corruption campaigner. Cartoonist Yuri Norshteyn broke that taboo on Saturday and criticised Putin over the jailed lawyer's death in 2009. Norshteyn said: "I think Sergei Magnitsky died of a failure of heart on Putin's part and on the part of the prison boss." The comment referred to Putin's statement that Magnitsky had "died not from torture, nobody tortured him, but from a heart attack." The Kremlin's own human rights council has said he was probably beaten to death.
