We explore the possible enhancement of the direct CP-violating parameter ε′/ε in the general left-right model based on the SU(2) L×SU(2)R×U(1) gauge group. The mixing matrix of right-handed quarks, VCKMR. is observable in the left-right model, and provides a new source of the CP-violating phase. We calculate the parameter ε′/ε in the left-right model and show that the new phases from VCKMR can yield a sizable contribution to the direct CP violation, enough to satisfy the recent measurements of Re(ε′/ε) from Fermilab KTeV and CERN NA48 experiments.
