A British woman born in the UK to unmarried parents has been left stranded in Spain after being refused boarding on a flight home to London under new Home Office rules that came into force on 26 February, requiring dual nationals to present a British passport or pay £589 for a "certificate of entitlement" before travelling to the UK. Natasha Cochrane de la Rosa, 26, who holds a Spanish passport through her mother, had previously travelled freely on it under EU free movement rules before Brexit, but was turned away at the departure gate without prior knowledge of the change; a British birth certificate and driving licence were not accepted as sufficient documentation. Critics argue the government failed to adequately publicise the new rules through airports or targeted outreach, and several other dual nationals have reported missing funerals, family reunions, and weddings as a result, while the Home Office has rejected calls for a grace period.
