Reports in the national media say that lawyers working on behalf of high street retailers are planning a lobbying campaign to alter the Sunday Trading Act 1994 and allow shops to open for longer on a Sunday.
Current laws say that retailers are only allowed to open for six hours on a Sunday.
However, retailers will lobby the Department of Trade and Industry to change the legislation.
A survey conducted by retail lawyer Bond Pearce last year found that two thirds of retailers would open for longer on a Sunday if the law allowed them to.
Kevin Hawkins, director general of the British Retail Consortium said: “Where there is clear customer demand for more flexible opening on Sunday, then it would not surprise me if retailers wished to be able to meet those demands.”
