Foreign Policy's list was compiled by Ian Bremmer, president of the Eurasia Group and FP blogger. Whilst topping the list Vladimir Putin did not win the number-one slot which Bremmer left empty.
reported Bremmer explained the top slot was left bare because "in a G-Zero world, everyone is waiting for someone else to shoulder responsibility for the world's toughest and most dangerous challenges."
Taking third place after Putin is Federal Reserve chairman Ben Bernanke, followed by Merkel, Obama, Mario Draghi, China's Xi Jinping, Ayatollah Ali Khamenei, Christine Lagarde, and Saudi King Abdullah.
Putin and Lagarde are awarded a higher rank on the Foreign Policy list than on the Forbes list
of most powerful people. British Prime Minister David Cameron, who was ranked tenth by Forbes, failed to make it into the FP's top ten.
Bremmer explained why Putin took the top slot, saying: "In Russia's personalised system, this is still the person who counts. He isn't as popular as he used to be, and his country has no Soviet-scale clout or influence, but no one on the planet has consolidated more domestic and regional power than Putin."
puts forward the views of some Russian experts on Putin's ascendancy in the FP list. Mikhail Remizov, President of National Strategy Institute, explains it succinctly, saying: "There are no high-profile leaders on the global arena now like those who lived in the second half of the 20th century. And among modern politicians, Putin looks like a reminder about hefty leaders who lived in the 20th century."
