Instore, the value retailer, saw like-for-like sales fall 1.9% for the 19 weeks ended July 11. Group sales were 0.3% up on last year.
Instore said it continued to trade at a loss but that shareholders should be aware that the chain has historically made a loss in the first half of the year.
As a result of shareholder acceptance of an offer for Instore from Seaham Investments directors Dr Christo Wiese, Cornus Moore and John Gnodde resigned from Instore earlier this month.
In addition Instore chief executive Peter Burdon will leave the group on July 15.
