New results on kaon decays from NA48/2

Recent results from the NA48/2 experiment are presented. The $\pi \pi$ scattering lengths $a_0^0$ and $a_0^2$ have been extracted from the cusp in the $M_{00}^2$ distribution of $K^{\pm }\to {\pi }^{\pm }{\pi }^0{\pi }^0$ decays and from the $K^{\pm }\to {\pi }^{+}{\pi }^{-}{e}^{\pm }\nu$ phase shift $\delta$. Branching ratios and form factors have been measured for {$K^{\pm }\to {\pi }^{\pm }\gamma \gamma$}, {$K^{\pm }\to {\pi }^{\pm }\gamma e^{+}{e}^{-}$} and {$K^{\pm }\to {\pi }^{\pm }{e}^{+}{e}^{-}$} decays and are also summarized here.
