BRUSSELS, Nov 27 (Reuters) - Finnish liberal Olli Rehn will oversee efforts to revive Europe's economy and France's Michel Barnier will have an important role reforming financial services in the new European Commission unveiled on Friday.

Jose Manuel Barroso, president of the European Union's executive, announced a 27-person team which he said would make boosting economic growth its priority and described it as a "perfect blend of experience and new thinking".

Rehn takes over as economic affairs chief from Spaniard Joaquin Almunia, who will be competition commissioner in a line-up that includes a climate change portfolio, underlining the importance the EU attaches to combating global warming.

"In five years' time, I want this Commission to have been instrumental in leading Europe out of the economic crisis towards a competitive economy that provides sustainable growth," Barroso told a news conference.

The formation of the Commission, which has strong regulatory and law-making powers, is the latest stage in the EU's efforts to increase its influence after the economic crisis and follows ratification of a treaty to make decision-making smoother.
