Luxembourg-based broadcaster CLT-Ufa has named Didier Bellens chief executive officer and Ewald Walgenbach chief operating officer.

Bellens takes over from joint chief executives Remy Sautter and Rolf Schmidt-Holtz who were appointed to represent CLT and Ufa when the two companies merged three years ago. The appointments will take effect on March 10.

Bellens is currently managing director of Groupe Bruxelles Lambert, co-chairman of the executive committee of CLT-Ufa and chairman of the board of directors of Audiofina, which is the co-controlling shareholder of CLT-Ufa alongside German media group Bertelsmann. Walgenbach moves from being head of television in Germany, production and rights at the company.

Meanwhile Schmidt-Holtz will assume a newly created post as "chief creative officer" in charge of Bertelsmann's internet strategy. Michael Dornemann, currently responsible for music and television on the group's executive board, will "concentrate on his Bertelsmann Music Group activities," the company said.
