Exclusive - Fortum set to gain EU antitrust approval for Uniper deal - sources

BRUSSELS (Reuters) - Finnish utility Fortum is set to gain unconditional EU approval to acquire a 46.65 percent stake in German energy group Uniper <UN01.DE> from E.ON <EONGn.DE>, three people familiar with the matter said on Monday. State-controlled Fortum's bid has run into opposition from Uniper, which said that the combination would make little sense given its heavy exposure to gas and coal-fired power plants while Fortum's focus is on clean technologies.

The European Commission is scheduled to rule on the 3.8 billion euros (3.4 billion pounds) deal by June 15.
