After more than a year of controversy, the ban on full face veil in France has just come into effect. But some women are already vowing to defy the restriction, Al Jazeera's Tim Friend reports from Paris. As the extreme right wing gains increasing popularity in France, President Sarkozy has been accused of trying to win back votes ahead of next year's presidential election by deliberately stigmatising Muslims. The government vehemently denies this, and argues that the full veil is a symbol of male oppression.
