Dear Fallen
I really appreciate your advice. Although it may have sucked out the last hope I had! I have found a document issued by the Home Office with guidance to the passport office called “Names Aligning on Foreign Documents”, as it is legally required to have two names under Spanish law it should be possible for this to be taken in consideration according to that document. I am just typing a new letter to them as the phone is useless- just cuts off with lines too busy! I admire your grit in holding on when you did get through.
