Recent results from the NA48/2 experiment are presented. The ππ scattering lengths a00 and a02 have been extracted from the cusp in the M002 distribution of K^± → π^± π0 π0 decays and from the K^± → π+ π- e^± ν phase shift δ. Branching ratios and form factors have been measured for K^± → π^± γγ, K^± → π^± γe+ e- and K^± → π^± e+ e- decays and are also summarized here.
