A British Member of Parliament from the ruling Labour party, Gerald Kaufman, has called for economic sanctions against Israel, including cutting off arms supplies, to force it back to the negotiating table with the Palestinians.
"It is not enough for the world community, including our own Government, to condemn the Israeli Government's brutal policies of repression," he said, addressing members of his Manchester constituency.
"Only widespread economic sanctions on Israel, together with cutting off arms supplies, can make any impact on this Government without a conscience".
Mr Kaufman, himself Jewish, said US President George W Bush's father, the former president Bush, had "understood the importance of forcing the Israelis to the conference table by imposing economic sanctions on a previous Likud Prime Minister, Yitzhak Shamir".
Mr Kaufman, once a frontbench Labour foreign affairs spokesman when the party was in opposition, criticised a decision by Mr Bush to receive Mr Sharon in Washington.
