I am wording the letter as advised. Do I need to sign it as well?

Thanks for the reply. I will reply as advised. If you can find the Morrisons Manger id, could you please give it to me. Meanwhile I will also try to search it on the website. Thanks

Thanks to both of you for your replies. So from armadillo71 message, does it mean that there is no point in defending the case with PE. Instead just try to go for POPLA. Is this correct? I will also try to speak to Morrisons rep. but even if they assure me that they will get the charge cancelled, how will i get confirmation that PE will not come back later with a court summon as I will not be paying them? Will they be sending any confirmation if Morrisons asks them?

Hi, I request for somebody's attention in helping me out here. Yesterday, I received a PCN in the post for £85 (£50 if paid within 14 days) from PE with ANPR showing my number plate overstaying 39 minutes more than the prescribed 2hours max. stay at Morrisons. I did go to the car park on the mentioned date but there was a massive traffic jam because of Guy Fawkes night and it took me 45 minutes to get out of the parking lot, all the time standing in the jam. I have gone through the threads and almost all of them refer to the cases where there is no traffic jam causing delays. I have to reply back to them but I am confused whether to go the regular route (the standard reply templates on this website) and question their GPEOL or should I mention them the reason for delay as Traffic Jam and refute their claim. If in my response I am mentioning the reason for delay as traffic jam and referring to myself as the registered keeper would it be better to put it as..... "I have been informed by the driver about the delays due to traffic jam....." or would it be better to just say about the traffic jam directly without referring to the driver part (which may/may not highlight me as the driver)? Any advice is greatly appreciated.
