A German far-Right party is attempting to stop the construction of a mosque in the first major test of its anti-Islam policy.

The Alternative for Germany (AfD) party, which is currently third in the German opinion polls, has announced that it will oppose plans to build the first mosque in the eastern state of Thuringia.

The project is “part of a long-term land grab” by Muslims, Björn Höcke, one of the party’s most senior leaders, claimed.

The party has called for public protests under the slogan “No mosques in Thuringia without the people’s consent”.

It announced it will try to block the mosque in the Thuringia state parliament.

The move will add to concerns over the resurgent far-Right and put the party on a collision coursse with Germany’s estimated 4m Muslim residents.

The AfD inflicted heavy losses on Angela Merkel in regional elections in March, campaigning on opposition to her “open-door” refugee policy.
