BRUSSELS (Reuters) - French carmaker PSA Group PEUP.PA secured unconditional EU antitrust approval on Wednesday to acquire General Motors' GM.N German unit Opel, a move which will help it better compete with market leader Volkswagen VOWG_p.DE.

The European Commission said the deal did not pose any competition concerns.

PSA, the maker of Peugeot and Citroen cars, has pledged to return Opel and its British Vauxhall brand to profit.
