I was sad to have to hand in my old F1250 (which did have my signature on it if my memory is still working) about two years ago. It had always worked for me wherever. I had a brilliant idea - I got a National Identity Card which did have my signature on it and worked as a passport in EU countries. That nice Mr Cameron scrapped them about a week after getting into No 10 and only after I had had my shiny new card a month!
Back to the drawing board.
