The determination of the mixing-induced CP-violating phase ϕs in the B0s - B0s system is one of the key goals of the LHCb experiment. Using several B0s decay modes it has been measured by the LHCb collaboration exploiting the Run I data set. The first observation of the B0s → ηcϕ and B0s → ηcπ+π- decay modes which can be used to measure ϕs with Run II data is presented.
