The Association of Convenience Stores has urged the government to reject fresh calls for a relaxation of Sunday Trading legislation. Sainsbury and Safeway both called for a change in the law limiting large stores from opening for more than six hours on Sundays. Suggestions include a three-hour extension that could be tacked on to current legislation without taking up reams of parliamentary time. Sainsbury chief executive Sir Peter Davis said he would like the flexibility to open for a "couple of extra hours" at certain times of the year, such as the run up to Christmas. Tesco, Asda and Waitrose said they were satisfied with current arrangements, although few doubted they would follow suit if rivals were successful in their bid. Safeway director of communications Kevin Hawkins said Safeway had not consulted the government on the issue since autumn 2000, and would first seek talks with other retailers to see if they wanted to revisit the issue. ACS chief executive David Rae said there was "no appetite" for a change and said he had been reassured by the government it had no intention of tinkering with the law. {{NEWS }}
