Van Mildert is set to close its store in the Intu Metrocentre shopping centre, Gateshead, Drapers has learned.
The closure will leave Van Mildert with six UK stores, in York, Darlington, Hull, Glasgow, Sheffield and Braehead.
Meanwhile, fellow Sports Direct-owned fascia Flannels will open a new store at the shopping centre on Thursday.
Flannels is also set to open a store in Swindon later this year, having recently opened in Sunderland and Plymouth. It acquired the freehold to a property on the corner of Oxford Street in April this year and will have 13 stores when all are open.
Drapers has contacted Sports Direct for a comment.
