Mediaset has acquired the 11% stake in its Mediaset Premium business held by the Spanish telco and broadcaster Telefonica.
It means that Mediaset will now hold 100% of the share capital in the terrestrial pay-TV business.
No details of the transaction have been released.
Telefonica originally bought the stake in 2014 for €100 million. Subsequently, Mediaset Premium has become the centre of a fractious dispute between Mediaset and the French media giant Vivendi.
