Kenyan President Mwai Kibaki and opposition leader Raila Odinga have signed an agreement to end a political crisis that followed a disputed presidential election held in December.

According to the deal, a coalition government, which includes a new position of prime minister, will be formed.

The president has expressed his resolve to implement the agreement.

"My government will fully support implementation of the agreement reached at the national dialogue and reconciliation process, until we achieve the results we all want."

Odinga says the opposition will also support the agreement.

"With the signing of this agreement, you opened a new chapter in our country's history, from the era of confrontation to the era of cooperation."

Meanwhile, chief mediator Kofi Annan says that the work on the government structure has successfully been completed.

"Today we have reached an important staging post but the journey is far from over, in fact it is only beginning. The real challenge now is for President Kibaki and honorable Raila Odinga to work together to heal and reconcile this nation, working jointly to implement the reform agenda which they have agreed and sustaining the effort until the job is done."

The prime minister will supervise and coordinate business in all ministries. Two deputy prime ministers will be recommended by coalition parties.
