Human Rights laws do not permit states to make a citizen stateless, by depriving them of their nationality.
Yes, Britain has withdrawn / cancelled citizenship of nationals who have gone abroad to fight as mercenaries or Jihadists. However those citizens have initially dual nationality, so are not made stateless.
Five of the dual nationals deprived of their citizenship were British Pakistanis, while two were of dual British and Sudanese nationality. The remaining six were Australian, Iraqi, Russian, Egyptian and Lebanese dual nationals.
Does that answer your question Phoenall?
I never posed any question I stated as fact that you and your fellow ISLAMONAZI PROPAGANDISTS were wrong and that there is no International Law that says that a nation cant refuse to accept for citizenship. In the UK's case they have all been muslims
