  Results from the Belle and BaBar experiments on measurement of the weak angle
phi_3 using a Dalitz plot analysis of the KSpi+pi- decay of the neutral D meson
from the B+=>D(*)K(*)+ process are presented. The method employs the
interference between D0 and D0bar to extract the angle phi_3, strong phase
delta and the ratio r of suppressed and allowed amplitudes.
