The measurement of the decay-time dependent charge parity (CP) asymmetry in $\D^0 \to \pi^+ \pi^-$ and $\D^0 \to K^+ K^-$ is presented using proton-proton collisions. The data was recorded at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 $fb^{-1}$, with the LHCb detector. Neutral $D$ mesons which arise from semi-leptonic decays of b-flavoured hadrons are used.
