  T2K is an off-axis long baseline neutrino oscillation experiment optimised to
measure theta13 and deltaCP using a muon neutrino beam. The most sensitive mode
is to look for electron neutrino appearance, and the dominant background for
such measurements is the intrinsic electron neutrino component in the beam
itself. A selection is made using data from the off-axis near detector (ND280)
to detect charged current (CC) electron neutrino interactions; these are split
into events with no pions in the final state (nue CC0pi) and the remaining CC
interactions (nue CCother). This strategy will both improve the constraint of
the intrinsic background by this analysis and allow a measurement of the CC0pi
cross section
