N2 - Measurements of CP observables in B$^{±}$ → DK$^{*±}$ decays are presented, where D denotes a superposition of D$^{0}$ and $ {\overline{D}}^0 $ 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 K$_{S}^{0}$ 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 $ \sqrt{s}=7 $ TeV, 8 TeV and 13 TeV, respectively. The sensitivity of the results to the CKM angle γ is discussed.
