DESCRIPTION:T2K is a long-baseline neutrino oscillation experiment in Japa
 n. An intense muon-(anti)neutrino beam produced at the Japan Proton Accele
 rator Research Complex (J-PARC) in Tokai is sent towards the \nMozumi mine
  some 295 km away. There\, the giant Super-Kamiokande water Cherenkov dete
 ctor sees a narrow-band beam peaked at 600 MeV. The baseline to energy rat
 io is finely tuned for studying oscillations at the so-called atmospheric 
 neutrino squared-mass splitting. The beam is also sampled 280 m  downstrea
 m of the neutrino production target by a series of finely-segmented solid-
 scintillator and time-projection-chamber detectors. Observing changes in t
 he neutrino beam between the near and far detectors allows oscillation par
 ameters to be accurately extracted.\n\nRunning in neutrino mode\, T2K perf
 ormed the most precise measurements of muon-neutrino disappearance and obs
 erved\, for the first time\, the appearance of electron neutrinos in a muo
 n-neutrino beam\, Since 2014\, T2K has been running primarily in antineutr
 ino mode aiming to obtain direct evidence for neutrino CP invariance viola
 tion. I will discuss the T2K analysis strategy and sensitivity in detail\,
  and present recently published results from a joint 3-flavour analysis of
  all neutrino and antineutrino data which disfavours CP conservation at 90
 % C.L. Finally\, I will discuss future prospects and the potential extensi
 on of the T2K programme.
