A Swedish couple who wanted to call their son Superman have been told to find a new name by the authorities.

Sara Lindenger and Johan Leisten, both 28 from Gothenburg, wanted to call their son Staalman, the Swedish name for Superman, after their favourite comic book hero.

But authorities in Stockholm have disallowed the name saying it is not appropriate and could be unpleasant for the boy.

Lindenger said: “We only wanted to use it as one of his middle names. It would have been much worse to call him Phantom or Tarzan.”
