Tesco sent the following response:

"I can confirm that  we (Tesco) used to have a relationship with this factory: our sourcing department worked with the site specifically in the production of garments for the Homeplus business in Korea, a process which included regular ethical and technical audits.

"You may be aware that Tesco sold Homeplus in September 2015. As part of transitional arrangements, our sourcing team continued to work with a number of clothing factories on behalf of Homeplus for a period of time after it became independent from Tesco. That agreement has now come to an end; as such Tesco no longer has a relationship with that factory (i.e. no further orders pending or planned). I do not know if the factory has reverted to supplying Homeplus via another route."
