We have studied the intrinsic normal and superconducting properties of the oxypnictide LaFePO. These samples exhibit bulk superconductivity and the evidence suggests that stoichiometric LaFePO is indeed superconducting, in contrast to other reports. We find that superconductivity is independent of the interplane residual resistivity ρ0 and discuss the implications of this on the nature of the superconducting order parameter. Finally we find that, unlike Tc, other properties in single-crystal LaFePO including the resistivity and magnetoresistance, can be very sensitive to disorder.
