Sigmar Gabriel, Germany's vice-chancellor, has raised eyebrows over a video of him showing the middle finger to a group of far-Right protesters.

Mr Gabriel was at a visit to Lower Saxony on Friday, when he was accosted by a group of masked protesters holding banners bearing the slogan "Traitor".

"Man, your father loved his country, and what have you done to it? You're destroying it," a protester can be heard saying on the video, in a reference to Mr Gabriel's father, who was a Nazi.
