Arthur Wagner, a leading member of Alternative for Germany (AfD) in the eastern state of Brandenburg, resigned from the post of the party's state executive committee on January 11 citing "personal reasons," according to Andreas Kalbitz, AfD's chairman.
Kalbitz told CNN on Wednesday that he only learned about Wagner's resignation when he telephoned him a few days ago.
Wagner was first elected as an AfD representative in 2015 and was a member of the state committee responsible for churches and religious communities.
Kalbitz added that he was surprised at his sudden resignation. He maintained that there was "no pressure from the party" for Wagner to resign since the party supported "freedom of religion."
Originally formed as an anti-euro party in 2013, the AfD in recent times, has campaigned aggressively on an anti-immigrant, anti-Islam platform. It has strongly criticised the German Government's decision to allow more than a million refugees into Germany in 2015.
The party came third in last year's federal election, winning 12.6 percent of the vote.
Speaking at a press conference a week before the federal elections, then co-chair of the AfD Alexander Gauland said that orthodox Islam is "incompatible" with "the principles of the modern, secular, free and democratic law-bound state."
In the wake of terrorist attacks that have ravaged Europe in recent times, Germany's far-right parties have advocated the closure of mosques and ban Muslim women to wear the burqa. (ANI)
