Just wondered for those who have dual nationality, is it really necessary to have BOTH passports? I have an EU passport and a UK one and live in the EU. The UK one is trickier to renew and more expensive. Can I just renew the EU one or is there a risk that Pritti Patel will cut me off??! I've read that you should take both passports to travel but I am not sure that is actually true. I have travelled just on my UK passport without any problems. As it's not just me but the kids too, I would rather save money but not sure if it actually a bad idea. Thanks.
