The Times of London reports Brown, who arrives Tuesday, will reportedly introduce a plan requiring massive spending on a worldwide scale.
"There is no international partnership in recent history that has served the world better than the special relationship between Britain and the United States," Brown writes in an opinion piece published Sunday in the Times of London.
Brown's 21st century deal calls for "universal action to prevent the crisis spreading" and "action to kick-start lending so that families and businesses can borrow again." It also requires "reform of international regulation to close regulatory gaps" and "the creation of an international early warning system."
Brown, who has hinted at increasing Britain's tax cuts to boost that nation's economy, is expected to present his proposal during a joint session of Congress on Wednesday.
