Bryant will add chairman's job to roles as president and CEO in July

John Bryant, Kellogg's president and CEO, has been named chairman of the Special K and Pringles owner.

Bryant will become chairman of Kellogg's board of directors in July, replacing James Jenness.

Jenness, who has worked for Kellogg for four decades and was himself the US food group's CEO nine years ago, will stay on the board as a non-executive director.

He praised Bryant, who joined Kellogg in 1998 and became president and CEO in 2011.

"John has a deep understanding of all aspects of Kellogg Company's business and a clear vision of how we will deliver on our strategy and grow our business around the world," Jenness said. "His election to chairman demonstrates the board's confidence in his leadership."

Kellogg is battling lacklustre cereal sales in developed markets. It is revamping its production network worldwide to free up resources for advertising and marketing, as well as expansion in emerging markets.

The company will report its results for the first quarter of the year on Thursday (1 May).
