RTL and Bouygues, the parent group of France's biggest private TV network TF1, ended a plan to merge M6 and TF1 into a national television champion last month, saying demands by the French competition authority made it unworkable.

RTL was "inundated" with expressions of interest in its 48% stake in the French TV network after the collapse of the TF1-M6 merger plan, its boss Thomas Rabe said shortly after.

Rabe had added that going on with a sale of the M6 stake was only an option.
