Abstract	The preliminary result for the vector formfactor slope parameter in semileptonic K^{+} \to \pi^{0}e^{+}\nu decay \lambda_{+}=0.0307\pm0.0042 with \chi^{2}=1.15/ndf is published. This result is obtained from processing a part of the experimental data gathered in experiment "Serpukhov-167". This result for \lambda_{+} is in good agreement with the world data and our previous results.
