After summing large logarithms to all orders the CP-asymmetries in Delta S=0 and Delta S=1 decays are found as\n  a_{CP} (Delta S=0) = (2.0 +1.2/-1.0)%\n  and\n  a_{CP} (Delta S=1) = ( -1.0 +/- 0.5)%.\n  These results are much larger than previous estimates based on a work without summation of large logarithms. We further show that the dominant contribution to a_{CP} (\\Delta S=0 ) is proportional to (sin gamma) times |V_{cb}/V_{ub}|.
