  Recent NA48 results from detailed studies of $K_{L,S}\to \pi^+ \pi^- e^+ e^-$
and $K_S\to\pi^0 \gamma\gamma$ decay modes are presented. The results are based
on the data collected with the NA48 detector at the CERN SPS during the
1998-199 9 and 2000 data taking periods, respectively. Prospects for future
results on charged kaon decays are briefly described.
