A British couple have been left stranded in New York City for the next three months with a £130,000 ($200,000) medical bill after their son was born 11 weeks earlier than expected.

Katie Amos, 30, and her fiancée Lee Johnston, 29, were not prepared for their son Dax to be born at Lenox Hill Hospital in Manhattan during a Christmas trip to the city. The couple had planned the trip as a last holiday before their baby arrived.
