JC Penney has confirmed to just-style that Ken Mangone, executive vice president of product development, design and sourcing, has left after 35 years with the department store retailer. 

Mangone had held the role since January 2011 at the Plano, Texas based retailer which operates 1,100 stores. 

A spokesperson for the company said: "We wish Ken continued success and thank him for his years of service to JC Penney."

JC Penney saw its third-quarter sales slide earlier this month despite ongoing efforts to turnaround the business, which include lowering overall prices and adding in-store shops.  

As part of these plans the retailer earlier this year announced plans to cut around 10% of the staff at its corporate headquarters earlier this year.
