Mr Bush dismissed the idea of a "right to return" for Palestinian refugees to former homes in Israel. Praising Mr Sharon's courage, he said a new map was needed because the "realities" in the region had changed. Mr Blair gave a guarded welcome to the moves last night, calling on the international community to "seize the opportunity" to inject new life into the stalled peace process-But Palestinian premier Ahmed Qurei said the plan "kills the rights of the Palestinian people". He accused Mr Bush of giving himself "the right to make concessions on behalf of the Palestinians", adding: "We cannot accept this under any circumstances."
