The leader of the Alternative for Deutschland (AfD) party in Saxony-Anhalt has been called "the most dangerous man in Germany".
Ulrich Siegmund, a 35-year-old former perfume salesman, is on course to be elected as leader of the state of Saxony-Anhalt.

Niall is joined by Sky’s Europe’s correspondent Alistair Bunkall, who tracked down Siegmund at an AfD rally in Saxony-Anhalt.
