The D{sup 0} meson can decay to the wrong sign K{sup +} {pi}{sup -} state either through a doubly Cabibbo suppressed decay or via mixing to the {bar D}{sup 0} state followed by the Cabibbo favoured decay {bar D}{sup 0} {yields} K{sup +}{pi}{sup -}. We measure the rate of wrong sign decays relative to the Cabibbo favoured decay to (0.383 {+-} 0.044 {+-} 0.022)% and give our sensitivity to a mixing signal.
