The Association of Convenience Stores (ACS) and the National Federation of Retail Newsagents (NFRN) have called on members to write to their MPs explaining the negative impact that proposed changes to Sunday Trading regulations would have on their business and asking them to raise the issue with the Prime Minister." A template letter is available for retailers to download from the ACS website. Retailers are also encouraged to write their own letters, detailing their personal experience of the importance of Sunday Trading rules.
