Andrew Neil takes on US conservative Ben Shapiro
He has more than 2 million followers on Twitter, 600,000 YouTube subscribers and his videos on the Daily Wire channel rack up millions of views.
Ben Shapiro is a controversial figure but one of the US' leading conservative political commentators. His book, The Right Side of History: How Reason and Moral Purpose Made the West Great, is a New York Times bestseller.
In a spiky Politics Live interview with Andrew Neil, Mr Shapiro refers to an incident which took place between Trump campaign manager, Corey Lewandowski and Breitbart reporter Michelle Fields in 2016.
Although a charge was brought at the time against Mr Lewandowski, Florida prosecutors dropped the case.
This is an unedited version of their interview, which was terminated by Mr Shapiro
