A 16-year-old British schoolgirl has been left stranded in Denmark after she was not allowed to board a flight to London because of new UK border rules introduced on British dual nationals.

Hanne*, from Sussex, was stopped from boarding a flight home on 8 March after a weekend seeing her British father, who is an academic on a short work stint at a university in Copenhagen.
