From next week, Jones will inherit all of Minnec's responsibilities, which include client servicing, personnel, new business and marketing.
Last September, the merged networks' management team felt Minnec and Jones should share overall responsibility for the London agency.
Minnec, who was appointed by Howard Draft, the global chief executive office of DraftFCB, to oversee the London office in January 2005, says he plans to spend more time with his three children in Chicago.
Once there, Minnec intends to work with DraftFCB Chicago in a "special projects capacity", rather than in a full-time senior management role.
It brings to an end a two-year period in the London office, where Minnec oversaw Draft's operations, including last year's Interpublic-driven merger with FCB.
Minnec said: "It was a complex conundrum. But for the last two years, as well as presiding over the company, I've been flying between London and Chicago to maintain work-life commitments. I owe it to (my children) to move back home and spend some quality time there."
