My provisional license has just expired (I know, I know, but I do intend to learn to drive one of these days and it's my main form of ID). I went to renew it at the post office as without a passport can't do it online. The post office is one of the ones in a WH Smiths and had one poor guy running it alone who wasn't trained to help me.
How long do I have to renew it? I can make time in the week if it's urgent but if not would prefer to go back next week.
