President William Ruto has urged his newly reconstituted Cabinet to make service to the people of Kenya their first and only priority.
Speaking after they took oath of office on Thursday, Ruto said they should not let their interests come in between.
He encouraged them to also focus on delivering and implementation of programmes that will move the country forward.
"I urge you, therefore, to go forth and from this day, focus on delivery, and dedicate your time and effort to the implementation of the various strategies, programmes, and projects that the nation’s transformation demands.
"I encourage you to make the people of Kenya your first and only priority and to never let your own interests come in the way of your duties," the President said.
Ruto assured the new CSs of his full support in discharging their mandate to Kenyans.
He said that he will be leading by example as a good steward of public resources and accountability.
Ruto said the people of Kenya have made their expectations known in bold terms.
He added that they have also made their intolerance for failure, inefficiency, corruption, and ineptitude equally clear.
"As champions of the nation’s development agenda, you will be team players, servant leaders, faithful trustees, effective stewards of the people’s interests, and dependable custodians of their resources."
The President said that he is confident each of the CSs have what it takes to deliver on their mandates and to satisfy the people’s expectations.
Ruto insisted that the new Cabinet has started a journey that cannot fail.
"The women and men who have been appointed to serve the nation in the reconstituted Cabinet have today embarked on a mission that cannot and must not fail," he said.
"The privilege to serve in positions of such high responsibility has come to you with an immense duty to do everything in your power to ensure that Kenyans receive the best services from the government efficiently, without discrimination, and without delay," he added.
