FRANKFURT, June 23 (Reuters) - Sports car maker Porsche has sought German antitrust authority clearance for its plan to raise its voting stake in Volkswagen to 25.1 percent from 21.2 percent, Porsche said on Friday.
"The Stuttgart company expects quick approval of the plan from the cartel authorities. As soon as this happens, Porsche could conduct the planned increase in its stake," it said, although it had not yet decided when it would actually boost its stake.
