Measurements of CP observables in B± → DK*± decays are presented, where D denotes a superposition of D0 and D0 meson states. Decays of the D meson to K- Π+, K-K+, Π-Π+, K- Π+ Π- Π+ and Π- Π+ Π- Π+ are used and the K*± meson is reconstructed in the K0 S± Π final state. This analysis uses a data sample of pp collisions collected with the LHCb experiment, corresponding to integrated luminosities of 1 fb-1, 2 fb-1 and 1.8 fb-1 at centre-of-mass energies p s = 7TeV, 8TeV and 13TeV, respectively. The sensitivity of the results to the CKM angle is discussed.
