WASHINGTON – President George W. Bush's foreign policies may be unpopular in the Middle East, but Arab leaders showered his top diplomat with jewelry worth far more than a quarter of a million dollars last year.

While Bush himself didn't fare nearly as well, Secretary of State Condoleezza Rice raked in at least $316,000 in gem-encrusted baubles from the kings of Jordan and Saudi Arabia alone, making her one of top recipients among U.S. officials of gifts from foreign heads of state and government and their aides in 2007.

In England those items will be the property of the Crown and the State
Here does she have to declare gifts and as such and does that count as bribes for favours received or to be received?
