British Prime Minister Gordon Brown has met with the chairman of the U.S. Federal Reserve and delivered a foreign policy speech as he wrapped up a U.S. visit.

A spokeswoman at the British embassy says Mr. Brown had breakfast Friday morning in Washington with Fed Chairman Ben Bernanke.

The British leader traveled on to Boston, Massachusetts where he delivered a foreign policy speech at the John F. Kennedy Presidential Library and Museum.

Mr. Brown met Thursday at the White House with President Bush.  During a joint press conference, the two leaders said they discussed the strained global economy and what their countries are doing to address housing concerns, inflation and an international food shortage.

On foreign policy matters, Mr. Brown said he made no apologies for pushing to extend sanctions imposed by the United Nations Security Council against Iran for its nuclear development program.

He also praised Mr. Bush's leadership in the global fight against terrorism, and promised that Britain will continue to support the wars in Iraq and Afghanistan. 

Mr. Brown said the military effort in Iraq and Afghanistan must be matched with economic and development programs.

Earlier Thursday, the prime minister met separately with the three U.S. presidential candidates hoping to succeed Mr. Bush - Democratic Senators Barack Obama and Hillary Clinton, and Republican Senator John McCain.
