(Adds Qualcomm background)
BRUSSELS, Jan 24 (Reuters) - European Competition Commissioner Margrethe Vestager will hold a news conference at 1130 CET (1030 GMT) on Wednesday on a case involving anti-competitive practices.
The Commission, which announced the news conference in a statement, did not give further details.
EU antitrust regulators are expected to impose a multi-million euro fine on Qualcomm Inc for paying Apple Inc to use only its chips, a person familiar with the matter told Reuters on Tuesday.
The European Commission accused the company of the anti-competitive behaviour in 2015. The fine could in theory go as high as 10 percent of Qualcomm's annual revenue, which was $22.2 billion for its most recent fiscal year. (Reporting by Philip Blenkinsop; editing by Robert-Jan Bartunek)
