Framingham, Mass. Staples said Friday Peter Ventress, its international president, left to take the CEO position at an undisclosed U.K. company.
COO and president Mike Miles will assume responsibility for Staples International, effective Sept. 1.
Ventress joined Staples when the company acquired Corporate Express in June 2008.
In May, the company said profit fell by one-third, as customers ordered less merchandise and spent less money on each order.
