We propose a hybrid scenario incorporating type I and type II seesaw models for neutrino mass where CP symmetry has been broken by the complex vacuum expectation value of a singlet scalar field. Applying appropriate symmetries we show that such a framework can simultaneously explain the neutrino oscillation data and measured baryon asymmetry via leptogenesis. Further, the natural choice of parameters leads to a mixed leptogenesis scenario driven by nearly degenerate right handed singlet neutrino and scalar triplet fields for which we show a detailed analysis.
