LONDON — Roger Carr, chairman of the board, Todd Stitzer, chief executive officer, and Andrew Bonefield, all of Cadbury P.L.C., have announced their plans to resign from the company. The announcements come following the acquisition of Cadbury by Kraft Foods Inc., Northfield, Ill. The effective dates of the resignations have yet to be determined, according to the company.

“It has been my great pleasure and privilege to chair Cadbury for the past two years, and I would like to thank Todd Stitzer, my fellow board members and indeed all of my Cadbury colleagues for their valuable support and commitment in taking this great company forward in that period,” Mr. Carr said.

Mr. Stitzer, who has been c.e.o. of Cadbury for the past seven years, echoed Mr. Carr’s sentiments and added, “I wish Irene Rosenfeld and her team every success in taking Cadbury and its brands forward. They have pledged they will do their utmost to preserve Cadbury’s unique performance driven, value led heritage, and I urge all my colleagues to do their utmost to help them in this special task.”
