We present a new technique to extract information on the unitarity triangle from the study of B\ensuremath→K\ensuremathπ\ensuremathπ Dalitz plots. Using the sensitivity of Dalitz analyses to the absolute values and the phases of decay amplitudes and isospin symmetry, we obtain a new constraint on the elements of the CKM matrix. We discuss in detail the role of electroweak penguin contributions and outline future prospects.
