July 11 (Reuters) - German billionaire Mathias Döpfner

and private equity group KKR are negotiating a break-up

of media conglomerate Axel Springer, the Financial Times

reported on Thursday, citing people with knowledge of the

matter.

Under the terms of the separation, KKR and Canada Pension

Plan Investment Board, who together have the largest

shareholding in Axel Springer, would take control of its

portfolio of classifieds websites, including jobs platform

StepStone and real estate ads unit Aviv, the report said.

Döpfner, the chief executive of Axel Springer, and Friede

Springer, the widow of the company's founder, would assume

greater control of the group's media properties, the report

added.

KKR and Axel Springer did not immediately respond to

Reuters requests for comment.

Global news publisher Axel Springer houses brands including

Politico, Business Insider, Bild and Die Welt.
