  The NA48 experiment at the CERN SPS aims to search for direct CP violation in
the $K^0$ system through the measurement of ${\rm Re}(\epsilon'/ \epsilon)$
with high accuracy. In 1999 the NA48 collaboration has published its first
measuremen based on 1997 data. A new result, based on 1998 and 1999 data, is
presented in this article. The result, combined with 1997 data, ${\rm
Re}(\epsilon'/\epsilon) = (15.3 \pm 2.6)\times 10^{-4}$, contributes to the
precise determination of the size of direct CP violation.
