Datuk Seri Abdullah Ahmad Badawi and his deputy Datuk Seri Najib Tun Razak have reached an agreement on the right time for a leadership change, the prime minister said Friday, according to Bernama. Reiterating that he and Najib enjoyed good working relations, Abdullah said they have mutually agreed on the "best time" for a leadership transition. Abdullah raised the issue as some people were still suspicious of the relationship between him and Najib including Kelantan Umno leaders who raised the matter at the Kelantan Umno liaison committee meeting chaired by the Umno President here, Friday. "Datuk Seri Najib and I have decided on the right time for me to hand over the premiership to him. We've no problems and we enjoy good working relations. "The leadership change will definitely take place at the right time," he said at a luncheon with senior government officials and community leaders. Earlier, Abdullah chaired a two-hour Kelantan Umno meeting. Abdullah is in Kelantan for a one-day visit. Najib said in London yesterday that he would not challenge Abdullah for power because as a "true Umno man" he would not risk destroying the party his father had built. He described himself as a loyal party member who subscribed to an orderly leadership change, as has been the Umno convention. Abdullah said the people should stop speculating on his relationship with Najib as such talk was of no benefit to anyone. "It's important for everyone to see the relationship between me and Najib as very crucial to strengthen Umno and the government and to implement the development projects and programmes that have been planned," he said. The Prime Minister also expressed his gratitude to the support given to him to continue to lead the nation and Umno. He promised to work hard for the country, party and the people. "I really value and appreciate the support given to me. If I am accorded solid support, it will spur me to work even harder for the party and the government," he said.
