Study of CP violation and the precise measurements of
the Cabibbo-Kobayashi-Maskawa (CKM) provide
test of the Standard Model.
Recent measurements on angles and sides
of the unitarity triangle such as phi_1, phi_3, phi_s,
|V_{cb}| from ATLAS, BaBar, Belle and LHCb experiments
are summarized.
LHCb has performed amplitude analyses on 3 body B decays
and has studied the source of local CP asymmetry.
This study is also mentioned in this proceedings.
