Hi, I have dual nationality (UK and Australian) and I am due to fly to Australia end March, returning mid-April 2013.
My British passport expires early October 2013 (just under six month's left at the time I'll be re-entering the UK).
I will only be using my British passport to re-enter Britain upon my return (I'll be using my Australian passport to enter Australia).
Do I need six month's validity to re-enter Britain on my British passport?
