UKIP MEP Godfrey Bloom on Wednesday was ejected from the European Parliament in Strasbourg after directing a Nazi slogan at a German colleague.
Godfrey Bloom said "Ein Volk, ein Reich, ein Fuehrer" - one people, one empire, one leader - as Martin Schulz, leader of the Socialists & Democrats group, was making a speech.
Bloom was ordered out of the chamber and will face disciplinary measures.
According to the BBC, Bloom said he stood by his words, describing the leader of the socialist group in the parliament, as "a national socialist", a nazi.
Barry Madlener, MEP for Geert Wilders' Dutch right-wing populist party PVV, supported Bloom.
