According to a report in the Huffington Post, Congress president Sonia Gandhi is the 12th richest political leader in the world.
With $2 billion wealth, Gandhi is believed to be richer than the British Queen Elizabeth II, Sultan of Oman Qaboos bin Said and Syrian President Bashar Al-Assad.
To compile the list, Huffington Post compared each country's GDP per capita juxtaposed with a leader's personal net worth, just to show 'how different life is for the haves and have-nots'.
The list includes kings, presidents, sultans and queens. The richest leaders among the top 20 originated from the Middle East region.
The report puts Russian President Vladimir Putin on the top of the list with a wealth of $40 billion, followed by King of Thailand Bhumibol Adulyadej with fortunes worth $30 billion.
However, the HuffPost report does not clearly state how it has arrived at the conclusion.
