Retail conglomerate Tengelmann is preparing to overhaul its German Kaiser’s Tengelmann supermarket network and is considering selling some of the stores in order to lift the network’s profitability, according to local trade press.

The chain consists of about 710 stores nationwide, but the review is expected to focus on trimming its operations in the central Rhine-Main-Neckar region.

Edeka’s Südwest division is already rumoured as a potential buyer of stores in the area. The measures are also expected to affect the banner headquarters in Viersen, which employs 600 staff.
