We report a search for charmless hadronic decays of neutral B mesons to the final state K⁺K^-π⁰0. The results are based on a 711 fb^-1 data sample that contains 772x10⁶ $$B$$$\bar{B}$$ pairs, and was collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺e^- collider. We find the first evidence for this decay with a significance of 3.5 standard deviations and measure its branching fraction as $$\mathscr{B}$$(B⁰ --> K⁺K^-π⁰) = [2.17 ± 0.60(stat) ± 0.24 (syst)]x10^-6.
