London: A mother cannot name her daughter 'Cyanide', a British court has ruled in a landmark case, saying her unusual choice might harm her children. The woman, who also chose the name Preacher for the girl's twin brother, insisted that she had a right to name her own children. But the mother, from Powys, Wales, was thwarted by top judges yesterday.

In the first case of its kind, Appeal Court judges ruled that it was an "extreme" case and that the mother's "unusual" choices might harm her children.
