KISII, Kenya (Reuters) - Kenyan President Daniel arap Moi said on Thursday that constitutional reforms enacted by parliament two months ago made it impossible for him to rig elections on December 29. Moi, aged 73, also told Reuters in an interview that the West had wrongly imposed democracy on Africa in total disregard for local realities. But he said he would win the vote anyway. Nine million Kenyans aged over 18 have registered to vote in presidential and parliamentary elections in which Moi, in power since 1978, is running for a fifth term he says will be his last. Moi`s main challengers are Mwai Kibaki, Raila Odinga, Michael Kijana Wamalwa and Charity Ngilu, Kenya`s first credible woman presidential candidate. Opposition leaders say that KANU, in power since independence in 1963, wields state resources to unfair electoral advantage despite a reform deal hammered out in October. Under the cross-party deal, which followed months of often violent protest, parliament reduced the power of civil servants over politics, increased opposition access to state-owned media and established a body to review the constitution after elections. Moi also approved the appointment of 10 new members of the electoral commission nominated by opposition parties. The 21-member board also includes 10 KANU members, with the 21st, chairman Samuel Kivuitu, hand-picked by the president. Moi accused Kenya`s fragmented opposition leaders of being mere tribalists and said they were bad losers. Key issues include national unity in a country of multiple ethnic groups, as well as corruption and development. Kenya, despite coffee, tea and stunning tourist attractions, remains one of the world`s poorest countries. Moi, in a recourse to a familiar theme, said he had accepted Western-style democracy but castigated the West for imposing it on the world`s poorest continent. KANU restored multi-party politics in 1991 after sustained pressure from opposition leaders and the international community. Moi was due to address a rally in Kisii district, western Kenya, as part of a campaign tour.
