(Photo: PA/ Rui Vieira, Steve Parsons, Michael McHugh) THE MAY BANK HOLIDAY WEEKEND officially kicks off today and many of us can look forward to a day off and much needed lie in on Monday. Supermarket workers are no exception meaning the opening and closing times of major supermarkets are different to normal. To prevent you getting caught out, we have compiled a list of the temporary timing changes that you need to be aware of in Blackburn. The opening times of some specific stores may vary, so customers should check details on the company website before making their trip.
