Veolia unveiled on Wednesday an improved offer to buy 29.9% of the shares held by Engie in Suez. 

The water and waste treatment group Suez once again rejected Wednesday the "vague" proposals of its competitor Veolia, which had unveiled a little earlier an improved offer and concessions to buy 29.9% held by Engie in Suez.

While Engie meets Wednesday a board of directors to study this offer, which could be a first step towards a merger of the two French giants of the sector, Suez calls in a press release "to the Board of Engie and its shareholders not to not decide the future of Suez under the conditions and the timetable dictated by Veolia ", whose offer expires at midnight.
