Retail trade union Usdaw is to launch a Save Our Sundays campaign at its annual conference in Blackpool this weekend.

It wants to stop any deregulation of Sunday trading legislation, which would allow large stores to open for longer than six hours on a Sunday. “With 95% of our members opposed to any changes in Sunday shopping hours, because they want to spend quality time with their families, there should be some fireworks,” said Usdaw general secretary John Hannett.
