US President Donald Trump’s top economic adviser Gary Cohn is resigning, the White House has said.
It is the latest in a series of high-profile departures from President Trump’s team.
There has been speculation that Mr Cohn, a supporter of free trade, was angered by Mr Trump’s plans to impose tariffs on aluminium and steel imports.
In a statement released by the White House, Mr Cohn said it had been “an honour to serve my country”.
The 57-year-old former president of the Goldman Sachs bank had helped Mr Trump push through his sweeping tax reforms late last year.
