US Republican Senator John McCain announced he will stand as candidate for President of the United States in 2008 during an appearance on the Late Show With David Letterman last night.

McCain said although he was announcing his candidacy, a more formal announcement will be made next month.

He told Letterman, "The last time we were on this program, I'm sure you remember everything very clearly that we say, but you asked me if I would come back on this show if I was going to announce. I am announcing that I will be a candidate for President of the United States."

He added jokingly, "This is the announcement, you drag this out as long as you can. You know what I mean? You don't just have one rendition. You've got to go over and over. This is the announcement preceding the formal announcement!"
