A search is made for the highly-suppressed B   meson decays B+→K+K+π−B+→K+K+π− and B+→π+π+K−B+→π+π+K− using a data sample corresponding to an integrated luminosity of 3.0&thinsp;fb−1&thinsp;fb−1 collected by the LHCb experiment in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90% confidence level are determined to be B(B+→K+K+π−)<1.1&times;10−8B(B+→K+K+π−)<1.1&times;10−8 and B(B+→π+π+K−)<4.6&times;10−8B(B+→π+π+K−)<4.6&times;10−8.
