A member of the Swiss political party that pushed for the minaret ban is a convert to Islam:

Daniel Streich was a member of the Swiss People’s party (SVP), the political party that pushed the minaret ban initiative. Streich is a military instructor in the Swiss Army and a local politician in the commune of Bulle. Formerly a devout Christian, he converted to Islam–and kept it a secret for two years.

Streich has left the SVP, made his conversion to Islam public, and has denounced the SVP’s anti-Muslim campaign as a witch hunt.
