US President Barack Obama has announced his intention to stand for a second term in office in 2012.
Mr Obama’s team released a video on his official website and sent an e-mail to supporters announcing his plans.
The president has an online network of millions of Americans and his web campaign was widely seen as a key plank of his election success in 2008.
The announcement was widely expected, and his campaign team are set to file election papers this week.
Mr Obama does not actually appear in the video, posted on YouTube as well as the official campaign website. Instead supporters look back to the 2008 campaign and talk of their hopes for the 2012 bid.
