Abstract: The most precise current determination of the Unitarity Triangle angle $ϕ_3$ is presented. It is obtained using the decay $B^+ \to D^{(*)} K^+$, with Dalitz plot analysis of the subsequent $D \to K_S π^+π^-$ decay. The result is $ϕ_3 = 68^\circ ^{+14^\circ}_{-15^\circ} \stat \pm 13^\circ \syst \pm 11^\circ \model$.
