Sir Philip Green's Arcadia Group has announced plans to shut 23 stores, putting 520 jobs at risk, as part of a rescue plan.
Dorothy Perkins, Burton, Topshop and Topman stores have been earmarked for closure - although it remains unclear exactly which stores are affected.
The retail group's proposals will also see rent cut at another 194 outlets.
Arcadia chief executive Ian Grabiner said: "Against a backdrop of challenging retail headwinds, changing consumer habits and ever-increasing online competition, we have seriously considered all possible strategic options to return the group to a stable financial platform.
"This has been a tough but necessary decision for the business.
"We will ensure all potentially affected colleagues are kept fully informed as we seek approval from our creditors on today's CVA proposals."
