"Many people have come to me; barefoot, illiterate from around the country, some without even my agreement began collecting signatures for me."
Ramos Horta said he had already consulted leading East Timorese politicians and religious leaders and won their backing.
"I have consulted with my president, Xanana Gusmao, consulted with the bishops and I have decided to accept the burden."
However, he also said that he would not be upset if he was rejected by East Timor's voters.

"If the people, in their centuries old wisdom, decide to vote for someone else, there are plenty of candidates right now. It is positive [that] there are so many candidates.
"If the people, in their centuries old wisdom, decide to vote for any of them other than me I will probably be the only candidate in the world for any job who will celebrate my electoral demise."
Ramos Horta has long been a leading political figure in East Timor. His political career started when he was an activist against the Portuguese colonial government in the 1970s.
After East Timor gained independence and was then invaded by Indonesia in 1975, he was East Timor's representative to the UN, travelling around the world to plead his country's case.
In December 1996, he shared the Nobel peace prize with Bishop Carlos Filipe Ximenes Belo for their efforts to win independence for East Timor.
Since East Timor became independent in 2002, he has served as foreign minister and minister of defence, before becoming prime minister in July 2006.
