I am from Scotland but I am currently living in Oz. I have dual-citizenship and had previously had current UK & Australian passports so the last time I was home I left & returned Australia on Australian passport & entered UK on British one. All good.
Now my passports have expired & I want to make a trip home. Australian rules state that if you are a citizen you must enter as such therefore I know I must use my Australian passport to be allowed to return. I can't find any such rule on the UK passport website so am thinking that I could just renew the Australian passport & use that. Is there anyone here in similar circumstances that has done so i.e. entered the UK on another country's passport despite still being a UK citizen.
I did try to clarify with the UK passport office but got a very unhelpful person who told me rudely that she could not advise me on using another country's passport and couldn't tell me if a UK citizen was obliged to use their UK passport as that was advising about another country.
