British Prime Minister Gordon Brown plans to meet Thursday with all three presidential candidates while he is the United States for a three-day tour.

Brown, on his second visit to the United States since becoming prime minister, plans to meet separately with Barack Obama, Hillary Clinton and John McCain at the British ambassador's residence.

Brown arrives in the country Wednesday, and is also expected to visit Boston, the United Nations in New York and Washington, D.C., where he will meet with President Bush. His meetings will focus on the global economy, according to the prime minister's Web site.

Brown met with Bush at Camp David when he last visited the United States in July 2007.

McCain has already met with Brown in the United Kingdom. He traveled there last month as part of a week-long, multi-country tour.
