We discuss the determination of the CKM angles γ and α using recent data from non-leptonic B decays together with flavour symmetries. Penguin effects are controlled by means of the CP-averaged branching ratio B d → π ± K ∓. The information from (two solutions for φ d ), R b and γ allow us to determine β, even in presence of New Physics not affecting Δ B=1 amplitudes. In this context we address the question of to what extent there is still space for New Physics.
