The time-dependent CPV direct and mixing-induced asymmetries in
B^0->\pi \pi and
B_s ->K K decays have been measured at the LHCb experiment using data
collected during Run1 at centre-of-mass energies of 7 and 8 TeV,
corresponding to 3fb^-1.
The data set was also used for a measurement of time-integrated CP
asymmetries in B^0->K \pi and B_s->\pi K decays.
The results obtained supersede those of B factories /with much
higher precision.
No other experiment has ever measured CP violation in B_s -> K K decays.
The measurements of the time-integrated CP asymmetries are the most
precise from a single experiment
to date.
