Edit that last post! Do not reveal who the driver is. All of my questions were about the registered keeper. The parking company don't know who the driver is, neither should we.
Only one page of the notice has uploaded.
Once you've edited your post, the keeper could reply to the parking company along the lines of the below:
Dear Sirs,
I have received your parking charge notice _____ for vehicle registration mark _____. I am the registered keeper of the vehicle. I note that your alleged claim is against the driver, not the keeper. There is no obligation for me to name the driver and I will not be doing so. Because I as the registered keeper have no liability for this charge, I am unable to help you further, and look forward to confirmation that the charge has been cancelled.
Yours faithfully,
