BJ’s Wholesale Club has revealed that after months of disappointing sales Mike Wedge had resigned as president and chief executive. The US retailer has named its chairman, Herb Zarkin, as interim CEO.

“While the company has made great strides in its efforts to improve general merchandise sales and customer traffic, overall progress has not come as quickly as we had hoped and expected,” Wedge Zarkin said in a joint statement. “We agree that the company’s leadership team will benefit from a fresh perspective at this time.”

Wedge was named president and CEO in 2002. Zarkin has been chairman since 1997.
