On a wet evening in Suhl, in the former East Germany, a smattering of youthful faces were among hundreds lining up to hear from an unlikely idol - Björn Höcke, one of the most controversial figures in the far-right Alternative for Germany (AfD) party.

The Alternative for Germany still has pariah status among other major political parties in a country where far-right politics has long carried a stigma because of the Nazi past.

In recent years, far-right political movements have gained traction across Europe. Parties that once existed on the fringes are now entering mainstream debates and, in some cases, influencing policy.
