We present the numu to nue appearance and the numu disappearance results, using a total of 1.43 x 10^{20} protons on target collected with the T2K experiment. T2K is long baseline neutrino experiment in Japan with detectors located at J-PARC, Tokai,
and at Kamioka in the Gifu Prefecture, situated 295 km away from J-PARC. The muon neutrino beam is produced and measured at the near detectors at J-PARC whilst the neutrino rates after oscillation are measured with the Super-Kamiokande detector, at Kamioka. A total of six events pass all the selection criteria for numu to nue oscillations at the far detector Super-Kamiokande, leading to 0.03(0.04) < sin^2 2theta_{13} < 0.28(0.34) for deltaCP = 0 and normal (inverted) hierarchy at 90% C.L. The numu disappearance analysis excludes no oscillations at 4.3 sigma. At 90% C.L., the best fit values are sin^2 2theta_{23} > 0.84 and 2.1 x 10^{-3} < Delta m^2_{23} (eV^2) < 3.1 x 10^{-3}. Finally, we present an overview of the T2K plans from 2011 onwards.
Flavour mixing is described within the Standard Model by the Cabibbo-Kobayashi-Maskawa matrix elements. With the increasingly higher statistics collected by many experiments, the matrix elements are measured with improved precision, allowing for more
stringent tests of the Standard Model. In this paper, a review of the current status of the absolute values of the CKM matrix elements is presented, with particular attention to the latest measurements.
