A ban on burka-like Islamic veils is expected to be passed today by France's lower house of parliament.
It is a move that is popular among French voters despite concerns from Muslim groups and human rights advocates.
The ban on face-covering veils will go to the Senate in September, where it is also likely to be passed.
Its biggest hurdle will come after that, when France's constitutional watchdog scrutinises it. Some legal scholars say there is a chance it could be deemed unconstitutional and shot down.
The main body representing French Muslims says face-covering veils are not required by Islam and not suitable in France, but it worries that the law will stigmatise Muslims in general.
