It is shown that Einstein-Weyl (EW) equations in 2+1 dimensions contain the dispersionless Kadomtsev-Petviashvili (dKP) equation as a special case: if an EW structure admits a constantweighted vector then it is locally given by h = dy 2 -4 dx dt -4u dt 2 , Ξ½ = -4u x dt, where u = u(x, y, t) satisfie
