NANTES, France (Reuters) - French high-speed train to power engineer Alstom is set to sell its remaining 16.66 percent stake in the Saint-Nazaire shipyards to Korea's STX later this week, a trades union said on Tuesday.
Alstom confirmed the sale had been planned for a long time but could not comment on the timing or the amount.
Force Ouvriere trades union official Jean-Marc Perez called for a rapid intervention by the French state to buy the stake from Alstom instead of letting STX become majority owner.
The government has a 33.34 percent stake in Saint-Nazaire -- known for building luxury cruisers and warships -- since a 2008 pact between Alstom and a Norwegian group on the sale of the yards to comply with EU conditions on Alstom's financial support package. STX later absorbed shipyard assets from Kvaerner and Aker (Aker), including the French yards.
