French President Francois Hollande's call for convicted terrorists to lose their French citizenship if they have a second nationality has triggered uproar among those who see him adopting right-wing ideas that recall dark moments in France's history, AFP reports.

Ever since the French Revolution in the late 1700s, "le droit du sol" ("the right of the soil") has been a fundamental principle, giving everyone born in the country the right to citizenship.

But in the aftermath of November's jihadist attacks in Paris, Hollande announced to an extraordinary session of both houses of parliament that he would seek changes to the constitution so that dual-nationals could be stripped of their French passport.
