Brussels, 29/01/2002 (Agence Europe) - The Commission is expected to adopt two decisions on Monday aimed at setting out the methods for breaking up the Schneider and Legrand electrical materials group and the Tetra Laval and Sidel packing company. The two mergers were vetoed by the Commission because they breached competition rules in the European market. The different partners had already begun merging even before receiving the go-ahead from the European authorities and have to, for the time being, forestall merger proceedings. If DG Competition's project is followed by the College of Commissioners, Tetra Laval will be obliged to give up 94% of its holding in Sidel over the next nine months. The same deadline will apply to the sale of Legrand shares by Schneider (98% of shares) but this could possibly be extended to twelve months.
