Donald Trump has slipped down the rankings of America’s richest people, sliding 11 spots in the past 12 months to be named the 259th wealthiest person in the United States.

Before Mr Trump launched his presidential campaign, he was ranked by Forbes, in their 2014 listing of the 400 richest Americans, as being the 122nd richest.

He announced his bid for the White House in June 2015; by October of that year he had slid to being the 138th richest.

In October 2016, when he was in the final stages of the presidential campaign, he was ranked 156th on the list.

And by last year his place in the league had slipped further: the New York billionaire, by then in the White House, was 248th.
