The ANTARES and IceCube neutrino telescopes have both searched for neutrinosfrom dark matter annihilation in the Galactic Centre, putting limits on thethermally-averaged dark matter self-annihilation cross section $\langle\sigma_A \upsilon \rangle$. For WIMP masses above 100 GeV, the most stringentlimits were obtained by the ANTARES neutrino telescope, while for lower masses,limits achieved by IceCube are more competitive. The limits obtained by the twodetectors are of comparable order of magnitude for WIMP masses going from 50 to1000 GeV, making this mass range particularly interesting for a combinedanalysis. In this contribution, we present the limits of the first combinedsearch for dark matter self-annihilation in the centre of the Milky Way usingANTARES and IceCube. The model parameters and the likelihood method wereunified, thereby providing a benchmark for future dark matter searchesconducted by each collaboration. By combining data of both detectors, weobtained improved limits with respect to the original limits published by thetwo collaborations.
