Plan to Make Blair an Envoy a 'Done Deal'

A plan to make outgoing British Prime Minister Tony Blair the chief Mideast envoy of the so-called Quartet of Mideast peacemakers is a "done deal," an aide to Blair tells ABC News. An announcement could come as early as today.

The Quartet is meeting today in Jerusalem to discuss the Israeli-Palestinian situation. It is the first meeting of the group since Hamas seized control of the Gaza Strip.

The Quartet is made up of the United States, the European Union, Russia and the United Nations.

"Blair's appointment has been 150 percent approved," an unidentified official was quoted as saying by the Financial Times.

Blair and California Gov. Arnold Schwarzenegger met Tuesday to discuss the trans-Atlantic battle against global warming.

The pair held breakfast talks at 10 Downing St. in Blair's final meeting with a foreign official before he steps down as Britain's prime minister Wednesday.

Blair would not confirm the pending appointment but did talk of his commitment to Mideast peace.

In Washington, two U.S. officials said the proposal could be voted on as soon as Tuesday, with a formal announcement soon thereafter.

But one official said Moscow was balking at naming Blair to the post. They spoke on condition of anonymity because of the sensitivity of the negotiations.

President Bush has strongly backed Blair for the new job, and Israeli Prime Minister Ehud Olmert has expressed support for the idea that Blair could play a role in the Middle East.

However, the Financial Times said Gordon Brown, who will succeed Blair as prime minister, is described as unhappy with the proposal because it would distract from his plans to use economic incentives to promote reconciliation between Israelis and Palestinians.
