I have bad news for you: the next time you rent a flat you will unfortunately need to show ID. All part of the beloved UK Government's plan to now try to make everyone feel as unwelcome as possible.
I've recently even had to scan and send ID documents to banks to open new accounts now, which never used to be the case, they used to be able to do all the checks they needed behind the scenes.
(Oh, and that'll be a driving *licence* that you have... ;-) )
Biting the hand that feeds IT
