We study time dependent CP asymmetries in B⁰d,ₛ decays in the left-right model with spontaneous breakdown of CP. Due to the new contributions to B⁰- B⁰ mixing the CP asymmetries can be substantially modified. Moreover, there can be significant new contributions to the B-meson decay amplitudes from the magnetic penguins. Most promising for detection of the new physics in the planned B factories is that the CP asymmetries in the decays B--> J/ψKₛ and B--> ϕKₛ which are supposed to be equal in the standard model can differ significantly in this class of models independently of the results in the measurements of B--> Xₛ γ.
