Footfall fell in all regions across the UK and Ireland for the week to August 22, with the number of shoppers dropping 3.4% year on year.
Shopping centres were worst affected, down 5.9%, while high streets dropped 3.1% for the week.
Footfall in retail parks fell for the first time in 17 weeks with a drop of 1% compared to the same week in 2014.
Diane Wehrle, retail insights director at research firm Springboard, said: “No location escaped the downturn in visitors, with the UK as a whole falling 3.4% against the same week last year. On the surface, there were few pockets of positivity across the complete benchmark spectrum with only three regions (East, East Midlands and Scotland) experiencing a rise in retail park traffic.”
