A Banach space is said to be L-embedded if it is complemented in its bidual in such a way that the norm between the two complementary subspaces is additive. We prove that the dual of a non-reflexive L-embedded Banach space contains l ∞ isometrically. 2010 Mathematics Subject Classification: Primary 46B20; Secondary 46B03, 46B04, 46B26.
