People with dual British citizenship have been warned that they could be refused boarding a flight, ferry or train to the UK after February 25 unless they have a valid British passport.
The warning from the Home Office comes amid dozens of complaints from Britons living or travelling abroad who have suddenly found themselves at risk of being denied entry to the UK.
The problem arose due to a change to border controls on February 25, when everyone travelling to the UK will need permission to travel unless they are British or Irish citizens.
Short-stay visitors must apply for an Electronic Travel Authorisation, which costs £16. But dual nationals will, for the first time, be required to show their British passport to travel to the UK.
Otherwise they must pay what many consider a punitive price of £589 for a “certificate of entitlement” that they must attach to their second citizenship passport.
