During 2011 data taking, LHCb has recorded large samples of semileptonic B decays. These provide potential to study CP violation effects in all of the D0, B0 and B0s systems. For the former, the charge of the muon in B -> D0 μ ν X decays provides a novel procedure to tag the flavour of the neutral D meson at production, allowing competitive sensitivity for the measurement of the difference of CP violation asymmetries in D0 -> h+ h- (h= K,π). For the latter, integrated or time-dependent asymmetries between charge-conjugate final states probe CP violation in B0(s) mixing through the measurement of the parameter Afs (sometimes referred to as Asl). All of these measurements rely on data-driven techniques to obtain excellent control of systematic uncertainties. We present the status of the analyses.
