portswood.info understands that Sainsbury’s bid to extend its opening hours to allow its Portswood superstore to open from 7am to 11pm Monday to Saturday and 9am to 5pm on Sundays has been rejected. Restrictions will remain according to earlier planning approval. Currently Sainsbury’s advertises opening times of 8am to 9pm weekdays, and 10am to 4pm on Sundays.
