Steve Bannon Interview on Europe's Far-right and Cambridge Analytica

One man who knows how Donald Trump rolls is Steve Bannon. The former chairman of the hard, right-wing Breitbart News website was appointed by Trump as his chief strategist after helping run the presidential campaign. But while the White House may have broken ties with Steve Bannon he's still carrying on with the work that brought him to the President in the first place - flying the flag for right wing populism in the US and across the globe. Our Europe Editor Matt Frei went to meet him.
