I am a UK citizen that is currently in Hong Kong and will be going back to the UK for studies. I also have a Hong Kong Passport.
Before leaving the UK for summer, I had lost my passport and started the process for getting a new one. I also still have the application number to prove this. However, I left the UK before the process was complete and thus I don't have a UK passport with me.
I am going to go back to the UK as semester starts, but entering the UK using my HK passport isn't really desirable.
So my question is, would it be possible to re-enter the UK without my UK passport? Or would I have to enter with my HK passport then leave and come back again after getting back my UK passport? If not, which number should I be calling to get an official response? (Called around and kept getting redirected without getting an actual response)
Added: I literally just found the passport that I lost before this one was applied for.
