The Compact Linear Collider (CLIC) is an option for a future electron-positron collider operating at centre-of-mass energies from a few hundred GeV up to 3 TeV. Details will be presented on two recent physics benchmark analyses of electroweak measurements at CLIC based on full detector simulations and assuming centre-of-mass energies of 1.4 and 3 TeV. Vector boson scattering gives insight into the mechanism of electroweak
symmetry breaking. The processes $\mathrm{e^{+}e^{-}}\rightarrow\mathrm{WW}\nu\nu$ and $\mathrm{e^{+}e^{-}}\rightarrow\mathrm{ZZ}\nu\nu$ were studied using fully hadronic events which provide the full kinematic information on the final-state bosons. The expected precisions on anomalous gauge couplings are extracted. The process $\mathrm{e^{+}e^{-}}\rightarrow\gamma\gamma$ allows to search for deviations from QED. The expected sensitivities to a finite electron size and other scenarios are discussed.
