Concerns have been raised that drivers may be 'caught out' with fines after new parking rules were introduced at Waitrose supermarket.
The supermarket has reduced the period of free parking which they offer at their Church Street store from 120 minutes to 90 minutes.
They have also introduced an automatic number plate recognition (ANPR) system which uses cameras to identify the number plates of vehicles entering and leaving the car park to determine whether drivers have overstayed - so parking tickets can be issued where they have.
A Waitrose spokesperson said "We are still providing 90 minutes free parking in our car park with no obligation to make a purchase from us. The new system is designed to ensure we continue to look after our customers who have found it difficult to find spaces because of the increasing pressure our car park has come under, especially during busy trading periods, while still providing free parking for other shoppers visiting the town centre."
