U.S. presidential candidate Barack Obama has hit back at a new political advertisement approved by rival John McCain, comparing him to Britney Spears and Paris Hilton.
In the TV advert, Republican presidential candidate MCCain depicts his Democratic opponent alongside pictures of the two troubled stars.
A narrator charges: "He's the biggest celebrity in the world, but is he ready to lead?"
But the political advert has infuriated Obama's team, who has responded to the promo in a newly released statement.
His campaign spokesman Tommy Vietor says: "On a day when major news organisations across the country are taking Senator MCCain to task for a steady stream of false, negative attacks, his campaign has launched yet another. Or, as some might say, 'Oops! He did it again.'"
MCCain's campaign manager Rick David explains: "What we decided to do is find the top three international celebrities in the world, and I would say from our indications, Britney and Paris came in second and third.
"It is not our campaign that is trying to make him into an international celebrity. It's his campaign... I don't know Paris Hilton and Britney Spears but they are international celebrities, so, you know, apples to apples."
