Forbes magazine unveiled its "World's Most Powerful People" list on Thursday ranking U.S. President Barack Obama as the most powerful person in the world this year, among 7.1 billion people taken into consideration.

This year's list included head of governments, businessmen and even the magazine added famous Mexican drug lord Joaquin "El Chapo" Guzman Loera, the head of Mexico's Sinaloa cartel and one of the most wanted drug traffickers in the world.

According to Forbes Obama emerged "unanimously" as the most powerful person for the second year running.

"Obama was the decisive winner of the 2012 U.S. presidential election, and now he gets four more years to push his agenda," the magazine said."The President faces major challenges, including an unresolved budget crisis, stubbornly high unemployment and renewed unrest in the Middle East. But Obama remains the unquestioned commander in chief of the world's greatest military, and head of its sole economic and cultural superpower."

The second most powerful person in the world according to Forbes was German Chancellor Angela Merkel and the third is Russian President Vladimir Putin, according to Forbes.

"Angela Merkel, the chancellor of Germany, jumps up from #4 last year to take the runner-up spot on the list. Merkel is the backbone of the 27-member European Union and carries the fate of the Euro on her shoulders," Forbes magazine wrote.

Microsoft co-founder Bill Gates landed in the fourth position and Pope Benedict XVI on the fifth. The top-ten ranking also included Ben Bernanke, the Chairman of the U.S. Federal Reserve on No. 6, Saudi Arabia's King Abdullah bin Abdulaziz al Saud on No. 7, European Central Bank's President Mario Draghi on No. 8, the General Secretary of the Communist Party of China Xi Jinping on No. 9 and U.K's Prime Minister David Cameron on No. 10

Mexican magnate Carlos Slim ranked No. 11, New York Mayor Michael Bloomberg landed on No. 16, Brazil's President Dilma Rouseff in No. 18 and Facebook CEO Mark Zuckerberg on No. 25, dropping from last year's top-ten ranking.

Drug dealer "El Chapo" ranked as No. 63.
