Abstract Measurements of CP observables in B±DK± and B±Dπ± decays are presented where the D meson is reconstructed in the final states K±π, π±K, K+K, π+π, K±ππ+π, π±Kπ+π and π+ππ+π. This analysis uses a sample of charged B mesons from pp collisions collected by the LHCb experiment in 2011 and 2012, corresponding to an integrated luminosity of 3.0 fb1. Various \CP-violating effects are reported and together these measurements provide important input for the determination of the unitarity triangle angle γ. The analysis of the four-pion D decay mode is the first of its kind.
