Blackstone, the buy-out firm, has won its €3.1bn ($3.8bn) bid for Celanese, the German chemicals company, after 80% of shareholders accepted the offer at the last minute.

The company confirmed that shareholders controlling 15% of the voting rights accepted the bid on the day of the deadline, March 29 . This took acceptances above the 75% level Blackstone needed to be sure of debt financing. The result will allow Blackstone to complete Germany's largest take private.
