She also had to go through a very expensive process to renew her British passport last minute.
Silly system.
Some of that, though, is a side-effect of the ubiquitous "Bank ID" identity tool - which suffers from the same dependency on Apple/Google that the article complains about. Given the current political climate I think the EU is going to have to figure something out to address this sort of thing.
Frankly it strikes me as being rather silly to not have a British passport as a British citizen.
Yes, I personally am not deeply inconvenienced by this, but that doesn't make it ok. Others are on much tighter budgets than me.
If obtaining a passport from a country where you are a citizen is such a hassle for you, you must focus on the only logical solution.
