President Mwai Kibaki returned to Nairobi Sunday evening after a three day working tour of the coastal region.

While in Mombasa, President Kibaki and Prime Minister Raila Odinga hosted a successful three-day National Leadership Retreat for ministers, their assistants and Permanent Secretaries.

During the bonding retreat held at a Mombasa Hotel, national leaders resolved to uphold the principal of collective responsibility and abide by their oath of secrecy.

In a communiqué released at the end of the retreat, the national leaders agreed to foster unity and cohesion within Government by refraining from making adverse public utterances against fellow cabinet ministers and assistant ministers.

President Kibaki challenged the country's national leaders to single-mindedly resolve to overcome the critical challenges facing the Coalition Government and build a prosperous nation.

The Head of State also affirmed that together with the Prime Minister they were committed to fostering a common sense of destiny among the national leaders.

The Plane carrying the President and the First Lady touched down at Jomo Kenyatta International Airport shortly before 6.00 and were received by senior Government officials.
