A study is given of the problem whether or not, and how, the deviations from the exact ΔI=1/2 rule observed in the K→2π decays can quantitatively be explained as a consequence of electromagnetic corrections to a purely ΔI=1/2 weak interaction. A sort of the current× current type weak interaction is considered. It is shown that the experimental values of a pair of the amplitude ratios, A(K^+→π^+π^0)/A(K_<1^0>→π^+π^-) and A(K_<1^0>→π^0π^0)/A(K_<1^0>→π^+π^-), can consistently be explained from such a point of view if one considers the λ_7-like interaction, besides the usually adopted λ_6-like one, and takes the effect of the η-π^0 mixing into account. The effect of the possible vector meson intermediate states is found to be in a direction favorable for explaining these amplitude ratios if m_<K^<*+>>-m_<K^<*0>>>0. The implication of the fact that the λ_7-like term plays a more important role is discussed.
