Query: Large electroweak penguin contribution in B --> K pi modes   I discuss about a possibility of large electroweak penguin contribution in B
--> K pi. To satisfy several relations among the branching ratios, we need
large electroweak penguin contribution. The magnitude is larger than the
theoretical estimation in the SM so that it may be including some new physics
effects.
