Hi Sammy
Thanks for the info.
However I contacted the Home Office, and I recorded the Phone call, and they told me I can apply for naturalisation with my expired ID if I evidence otherwise that I have exercised my Treaty rights for 6 years or more.
Fortunately, I contacted my local authority, who deals with citizenship processes, who then contacted the Home Office themselves, and they got the same answer. They called me yesterday to tell me that.
In the meantime, I have an appointment with my local MP next week, to clarify this further.
I found out that with the Home Office we need to ask, and ask, and ask again, and clarify, and clarify again, because their staff are really inconsistent in their answers.
I think persistence is the best. Unfortunately for me to renew my ID is not possible because the embassy of my country is even more complicated than the Home Office. I've been here for many years now and they will simply not give me a new ID or passport unless i move back to where I was born (as if!).
cheers
