More allegations surfaced about U.N. ambassador nominee John Bolton Sunday, this time from the Brits.

"Newsweek reported, in its May 2 edition, that British Foreign Secretary Jack Straw complained about Bolton to then-U.S. Secretary of State Colin Powell in November 2003. Citing a "former Bush administration official who was there," Newsweek said Straw told Powell that Bolton -- Powell's undersecretary for arms control and international security -- was making it impossible to reach an agreement on Iran's nuclear program.

According to the official, Newsweek reports, Powell then turned to an aide and said, "Get a different view on [the Iranian problem]. Bolton is being too tough."

Newsweek said British officials 'at the highest level' persuaded the White House to keep Bolton off the negotiating team that ultimately convinced Libya to give up its nuclear program. Bolton was unwilling to support a compromise under which the United States would drop its goal of regime change in favor of 'policy change' in exchange for Libya's disarmament, the magazine reported."
