Dutch consumers authority ACM has said it wants more time to assess the possible takeover of RTL Nederland by Belgian media group DPG.

The watchdog said on Friday it is concerned that the €1.1 billion takeover would make DPG too dominant. Last year the ACM blocked a merger between RTL Nederland and Talpa, saying the combine would have too powerful a position on the commercial media landscape.

“Based on its investigation so far, the ACM foresees possible adverse effects of the acquisition on the quantity, quality, and pluralism of the general news landscape for consumers,” the agency said.

The ACM said it also planned further investigate the consequences of the acquisition on the position of both employed and freelance journalists.

DPG Media owns the Volkskrant, Trouw, AD and Parool newspapers and news service Nu.nl. It also owns radio stations QMusic and Joe. RTL Nederland’s brands include RTL 4, RTL5, RTL7, RTL8 and RTLZ as well as streaming service Videoland.

The two companies told the Financieele Dagblad last year they did not expect the ACM to block the deal.
