most powerful people on earth in the latest Forbes list that is topped by US President Barack Obama, who claimed back the spot in the glow of American successes against Osama bin Laden and Muammar Gaddafi.

Gandhi has been placed at the 11th place in the list and comes out as the most powerful Indian, and Forbes described her as a politician who has "twice refused to serve as prime minister, delegating that job to Manmohan Singh".

Singh himself is placed at the 19th place and is described by the influential magazine as an "incorruptible" Cambridge, Oxford educated economist.

Despite a poor popularity run at home, Obama, who was last year toppled by Chinese President Hu Jintao as the most powerful person in the world is again at the helm of the list, while Hu has slipped to the third spot behind Russian strongman Vladimir Putin.

The magazine said Hu's diminishing influence as he gives up political office was part of the reason why Obama was able to reach up even while falling down in popularity charts at home, so was America's continued supremacy in the world.

"Despite faddish American declinism, the US remains, indisputably, the most powerful nation in the world, with the largest, most innovative economy and the deadliest military," it said.

The US forces' success in eliminating its enemy number one Osama bin Laden and the US-led NATO forces' success in Libya are indicators of America's continued might in the world.
