A new measurement of the K+ → π+ π0 decay with significantly higher statistics and improved kinematic constraints was performed using E787 detector and K+ decays at rest. The branching ratio of the direct emission was determined. The decay spectrum indicated that the direct emission amplitude is consistent with being due to purely magnetic contributions comparable to the reducible anomalous contribution.
