For years at the height of his Apprentice fame the appeal of living, dressing, eating and smelling like Donald Trump showed few limits.

There were Trump steaks, Trump deodorant, Trump shoes, Trump vodka, Trump ties and, bizarrely, a Trump-branded urine test.

But the president's decision to trade TV stardom for frontline politics appears to have had a corrosive effect on the appeal of his brand name.

All but two of the 19 companies paying him to produce or distribute Trump-branded products when he joined the president race have stopped, according to The Washington Post.

The findings reflect Mr Trump’s transition from popular television personality to divisive Republican president over the last decade.

It also indicates that parts of the president’ business empire, now run by his two sons, have suffered since he entered the Oval Office.

In 2009, Mr Trump reported that his licensing partners sold $215 million worth of Trump-licensed goods across the world, according to The Washington Post.
