A new measurement of ℛe(∊′/∊) by the NA48 collaboration using data collected in 1998 is presented. The preliminary result is ℛe(∊'/∊) =(12.2±2.9 ( stat )±4.0 ( sys )) ×10-4. The combination with the previous measurement using the 1997 data yields ℛe(∊′/∊)=(14.0±4.3)×10-4. This result confirms the existence of direct CP violation. The uncertainty on this measurement will be improved in the future.
