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 ±π ∓π +π −, π ±K ∓π +π − and π +π −π +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 fb −1. 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.
