  The effect of weak annihilation and u-quark penguin contribution on the
branching ratio B -> K_1 gamma at next-to-leading order of alpha_s are
calculated using LEET approach. It is shown that the value of LEET form factor
remains the same in the range of unitarity triangle phase alpha favored by the
Standard Model. CP-asymmetry for above mentioned decay has been calculated and
its suppression due to the hard spectator correction has also been
incorporated. In addition, the sensitivity of the CP-asymmetry on the
underlying parameters has been discussed.
