B mesons provides an ideal laboratory for measurements of CP violation and searches for CPV beyond the Standard Model. Recent measurements of the mixing phases of the $B_s$ and $B_d$ mesons, $\phi_s$ and $\sin{2 \beta}$, using decays to $J\Psi$X final states are presented. In view of future improved measurements, a good understanding of pollution from sub-leading penguin topologies in these decays is needed. Those can be probed using suppressed decays like $B_s \to J/\Psi K_S$ and $B_s \to J/\Psi K^*$. Recent results on these decay modes are presented.
