OP, you get a free bite at this cherry if you submit reps before 7 Aug, so why not give it your best shot?
When I parked, I exited my car on its offside and went to the **** thinking that I'd parked wholly within the parking place and was within the free parking period so I headed off. I can see from the council's photos that in fact the nearside rear of my car was on the yellow line, albeit only marginally*, something which I hadn't seen from the driver's position.
I am sorry for this event and I will certainly take more care etc... Would the council pl exercise its discretion on the occasion etc...
IMO do NOT mention the attempted removal, at this stage it's not relevant.
*- a subjective assessment!
OP, out of interest why would you want to pay, GSV shows a free parking period of up to 15 mins between 10am and 1pm, your PCN is timed at 11.27!
