Russian President Vladimir Putin might be the richest man in the world, according to experts who believe he could have a net worth of $200billion.

The official richest man in the world, according to Forbes, is Microsoft’s Bill Gates with a net worth of $75billion.

During his nearly two decades in power, Putin’s net worth has been widely speculated, with the former KGB agent likely having private assets in real estate and company holdings.

One of the most quoted guesses of the 64-year-old’s net worth is political analyst Stanslav Belkovsky’s 2007 estimation of $40billion, but Bill Browder, author and a former fund manager in Russia, has said the president has a higher worth – upwards of $200billion.
