Abstract
The latest measurements of the individual time-integrated CP asymmetry in the Cabibbo-suppressed decays $D^0\to hh$ decays are presented. The results are based on $pp$ collision data, corresponding to an integrated luminosity of 3 $fb^{-1}$, collected with the LHCb detector at centre-of-mass energies of 7 and 8 TeV.
A combination of the asymmetries using both prompt and secondary charm decays is presented
\begin{align*}
A_{CP}(KK)$=(0.04\pm0.12(stat) \pm0.10(syst))\%, \\ A_{CP}(\pi\pi)$=(0.07\pm0.14(stat) \pm0.11(syst))\%.
\end{align*}

These are the most precise measurements from a single experiment. The result for $A_{CP}(KK)$ is the most precise determination of a time-integrated CP asymmetry in the charm sector to date, and neither measurement shows evidence of CP asymmetry.
