Former Danish Economy Minister Margrethe Vestager will be taking over as the European Union's powerful antitrust chief in November.

The EU said Wednesday the 46-year-old will take over from incumbent Joaquin Almunia when the 28-nation bloc's new executive Commission takes office.

The Competition Commissioner wields huge executive power in enforcing antitrust law for the EU, the world's biggest economy.

One controversial case Vestager is likely to inherit is the four-year-old investigation on whether Google is abusing its dominant position for Internet searches.

Vestager is a former economics and interior minister from Denmark's center-left coalition government.

Sweden's Cecilia Malmstroem wil be the new Commissioner for Trade in charge of negotiating free trade deals like the one being discussed with the United States. She currently serves as Home Affairs Commissioner.
