Greenspan: Trump populism 'a cry of pain'

Donald Trump's populism is "not an economic policy" but instead is "a cry of pain", says former Federal Reserve chair Alan Greenspan.

Mr Trump will not manage to attain 3% economic growth, as promised, but deregulation will help markets, he tells the BBC's Katty Kay as part of the 100 Days series.
