The victory of Barack Obama in the Democratic Party nomination race shows that the United States remains a land of opportunity, the Times of London wrote in an editorial on Wednesday.
"This moment's significance is its resounding proof of the truism about America as a land of opportunity: Mr Obama's opportunity to graduate from Harvard and take Washington by storm," the British daily wrote.
The newspaper said his victory also demonstrates "the opportunity that the world's most responsive democratic system gives its voters to be inspired by an unknown; the opportunity that outsiders now have to reassess the superpower that too many of them love to hate."
Obama on Tuesday laid claim to his place in history as the first black US presidential nominee after US media reported he had clinched his party's nomination by securing the 2,118 delegates needed.
"Win or lose in November, he will have gone farther than anyone in history to bury the toxic enmity that fuelled America's civil war and has haunted it ever since," wrote the Times.
