  We discuss the determination of the CKM angles gamma and alpha 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 \to
\pi^\pm K^\mp. The information from A_{CP}(B_d \to J/\Psi K_S) (two solutions
for phi_d), Rb and gamma allow us to determine beta, even in presence of New
Physics not affecting Delta B=1 amplitudes. In this context we address the
question of to what extent there is still space for New Physics.
