Abstract
We report results of the branching fractions for a number of charm B decays including $\bar{B}^{0} \to D^{*+}\pi^{-}$, $\bar{B}^{0} \to D^{*+}K^{-}$, $\bar{B}^{0} \to D^{+}\pi^{-}$ and $\bar{B}^{0} \to D^{+}K^{-}$ all measured using $772\times 10^6$ B-meson pairs recorded by the Belle experiment at the KEKB asymmetric-energy $e^+e^-$ collider.
The measurements provide a precise test of QCD factorisation.
We also report preliminary results for the branching fraction $\mathcal{B}(B^{+} \to D^{*+}_s(\eta,K^0_S)/D^{+}(\eta,K^0_S))$ and the time-dependent CP asymmetry in $B^0 \to \eta_c K^0_S$.
The latter measurement provides information on $\sin2\phi_1$.
