  The charge asymmetry in top quark pair production in the di-lepton $t\bar t$
channel using the ATLAS experiment at Large Hadron Collider is presented. The
asymmetry is studied in the distribution of absolute rapidity difference
between top and anti-top. The reconstruction of the $t\bar t$ system is based
on a leading order matrix element. The lepton charge asymmetry is also
presented. All results are consistent with the Standard Model.
