The ANTARES detector is the largest neutrino telescope in the Northern Hemisphere. Interactions of all neutrino flavours can be observed and reconstructed with good resolution. The track channel – events induced by muon neutrino charged-current interactions – allows to increase the effective detector volume by the long path travelled by muons in rock and seawater, with excellent angular resolution but limited energy-reconstruction precision. While it can be used only for events in a smaller volume, the shower channel – neutral- and charged-current electron and tau neutrino interactions – allows for a better energy resolution than the track channel. Exploiting its multi-year dataset, the complementarity of its field of view and its excellent reconstruction performance, ANTARES reaches the necessary sensitivity to independently investigate the cosmic neutrino flux reported by the Antarctic IceCube detector. The latest results of these all-flavour searches for a diffuse astrophysical neutrino flux will be presented in this contribution.
