One of Barack Obama's Middle East policy advisers disclosed yesterday that he had held meetings with the militant Palestinian group Hamas - prompting the likely Democratic nominee to sever all links with him.

Robert Malley told The Times that he had been in regular contact with Hamas, which controls Gaza and is listed by the US State Department as a terrorist organisation. Such talks, he stressed, were related to his work for a conflict resolution think-tank and had no connection with his position on Mr Obama's Middle East advisory council.

"I've never hidden the fact that in my job with the International Crisis Group I meet all kinds of people," he added.

Ben LaBolt, a spokesman for Mr Obama, responded swiftly: "Rob Malley has, like hundreds of other experts, provided informal advice to the campaign in the past. He has no formal role in the campaign and he will not play any role in the future."...

Presidential-elect Barack Obama has promised to improve U.S. relations with Egypt and Syria.

Aides said Obama had sent senior foreign policy adviser Robert Malley to Egypt and Syria over the last few weeks to outline the Democratic candidate's policy on the Middle East. The aides said Malley, who served in the administration of President Bill Clinton, relayed a pledge from Obama that the United States would seek to enhance relations with Cairo as well as reconcile with Damascus.

"The tenor of the messages was that the Obama administration would take into greater account Egyptian and Syrian interests," an aide said.
