The UK Parliament has recently addressed an important question: Can a British citizen travel to the UK using a non-British passport?
Below is the link: https://commonslibrary.parliament.uk/research-briefings/cbp-10344/
Where the uncertainty lies: what happens to British citizens who also hold passports from other European countries and sometimes have to travel with these passports – with the risk otherwise of losing their non-British nationality?
We are receiving many questions about this, but at the moment we cannot give a clear answer!
This raises an important legal question:
What are the actual consequences if a British citizen presents only their non-British passport?
It is not yet fully clear how carriers and border authorities will apply this in practice, particularly where dual nationality creates conflicting legal obligations.
We are currently following discussions and developments closely, but there is no definitive clarification yet.
We will keep you informed as soon as more concrete guidance becomes available.
For now, we recommend booking tickets using European nationality, if are a European citizen and you also have a British passport.
We will keep you informed.
