Russian President Vladimir Putin is to miss the funeral of the last Soviet leader, Mikhail Gorbachev, denying the man who failed to prevent the collapse of the Soviet empire the full state honours granted to Boris Yeltsin…Gorbachev, idolised in the West for allowing eastern Europe to escape Soviet communist control but unloved at home for the chaos that his “perestroika” reforms unleashed, will be buried on Saturday after a public ceremony in Moscow’s Hall of Columns.
