The European Commission has opened a formal investigation under EU State aid rules into Polish plans to grant aid towards a project by the Fiat group to produce a new generation of petrol engines in the Silesia region. At this stage, the Commission has doubts the aid meets the EU guidelines on aid to large investment projects in relation to the market shares and production capacities of the Fiat Group. The opening of a formal investigation gives interested third parties the possibility to comment on the proposed measure. It does not prejudge the outcome of the procedure.
