Kenyan President Mwai Kibaki has announced he will stand for re-election in December as the candidate of a new political alliance.
Mr Kibaki cited in his speech the achievements of his five year term
In a live television address Mr Kibaki said the grouping would be called the Party of National Unity.
He won in 2002 as a candidate for the National Rainbow Alliance.
His re-election bid was boosted earlier this month when the official opposition leader announced he would not be challenging Mr Kibaki at the next poll.
Mr Kibaki, 75, announced his bid at a meeting of his new allies in the capital Nairobi, listing achievements in his first term as free primary education, health improvements, and road construction.
"Things are getting better but we are far from where we want to be," he said.
"I will therefore be seeking support of all Kenyans so as to continue making our country an even better and greater home."
Mr Kibaki said his new alliance would include the Kenya National African Union (KANU), Ford Kenya, Ford People, Narc Kenya and Shirikisho among others.
Uhuru Kenyatta said he did not think he would win an election
Earlier this month, Kenya's official opposition leader Uhuru Kenyatta had said he would not contest December's presidential poll.
Mr Kenyatta said the former ruling Kanu party would instead seek an alliance with President Kibaki.
Mr Kenyatta, son of Kenya's first president Jomo Kenyatta, lost the 2002 election to Mr Kibaki.
Instead, Mr Kibaki is likely to face a challenge from a former ally, Raila Odinga, who heads the Orange Democratic Movement (ODM).
