The ballot count in Kenya's presidential elections has been rigged, says the running mate of Prime Minister Raila Odinga, who is trailing behind his rival, Uhuru Kenyatta."We have evidence the results we have received have been doctored," said Mr Odinga's running mate Kalonzo Musyoka.He said counting Monday's votes should be stopped but added that his comments were not a call for protest.The election chief rejected the claims, as has Mr Kenyatta's party."There is no room to doctor results whatsoever," said Independent Electoral and Boundaries Commission (IEBC) chairman Ahmed Issack Hassan.Earlier, the IEBC's Liliane Mahiri Zaja, told the BBC that no written complaint had so far been received about the way the votes were being counted.Counting has been severely delayed after the electronic system crashed.The Independent Electoral and Boundaries Commission (IEBC) has been holding closed-door meetings with diplomats, reports BBC Swahili's Idris Situma.More than 1,000 people were killed in the violence which broke out in 2007-08 after Mr Odinga claimed he had been cheated of victory by supporters of President Mwai Kibaki.Mr Kibaki is stepping down after two terms in office.Mr Kenyatta, who backed Mr Kibaki, is due to stand trial at the International Criminal Court (ICC) next month, accused of organising attacks on members of ethnic groups seen as supporters of Mr Odinga. He denies the charges.
