Former White House chief strategist Stephen Bannon will speak at a gathering of France's far-right National Front on Saturday and meet with the political party's controversial leader Marine Le Pen.

Bannon will headline the annual convention for the anti-mass immigration party in the French city of Lille, Reuters reports, as he travels across Europe meeting populist leaders in various nations.
