A family who were meant to be travelling to the Algarve for a £3,000 holiday were forced to cancel the trip because of a little-known Brexit rule.
The Gurd family were unable to board their flight because of a passport glitch - despite all their documents being in order and valid, according to the BBC.
Mum Nina Gurd was knocked back from the flight because despite her passport being due to expire in February 2023 it is not valid for travel to Portugal, and some other countries.
