Putin, a former KGB lieutenant colonel who was handed the presidency on the last day of 1999 Boris Yeltsin, served as president from 1999 to 2008, then as prime minister until 2012, and then again as president from 2012 to the present.
"I always think about it," Putin, 72, said when asked if he thought about the succession in a film by state television about Putin's quarter of a century as Russia's paramount leader entitled "Russia, Kremlin, Putin, 25 years".
