I hear many legal opinions that secularity is not possible with a State religion, faith in Allah and the starting words Bismillahir Rahmanir Rahim. This of course is not true because Great Britain has a State religion and a State Church and a religious preamble to all legislations ( as has the United States with its trust in God and Christianity) but none of these hinder secularity in practice because this is a  legal concept and not religious.
