Donald Trump has fallen more than 200 places on the Forbes annual billionaires list.

The US President, who made his name as a real-estate and reality tv mogul, has seen a dramatic fall in the rankings since the launch of his presidential campaign.

Trump was ranked as No. 776 out of 2,208 on this year’s list, with a net worth of $3.1 billion.

This marks a considerable drop from his position on the 2017 list, coming in at No. 544 on the ranking, with a net worth of $3.5 billion.

At the top-end of the list, Amazon (NASDAQ:AMZN) founder Jeff Bezos took the number one spot with $112 billion, followed by Microsoft founder Bill Gates, who came in at second place with $90 billion.

Forbes explained Trump’s fall as partly due to a downturn in the retail real estate market in New York City, alongside “the president’s polarizing personality is costing him business as well.”

Despite having taken office just over a year ago, Trump’s presidency has thus far been shrouded in controversy.

Notably, the Trump administration continues to be under investigation with regards to alleged Russian interference in the US election.

Most recently, The President’s top economic advisor Gary Cohn resigned due his strong opposition to the imposition of tariffs on steel and aluminium imports.

Mr Cohn is one of many of a series of high-profile exits from the Trump administration in recent months.

He follows the departure of Hope Hicks as communications director, who quit last week.

Other senior figures who left their role include former chief of staff, Reince Priebus, and the President’s former chief strategist, Steve Bannon.
