Bundotich Kiprop, who lost the Uasin Gishu governor election in August, has asked NASA leader Raila Odinga to 'retire in peace as Kenyans owe him nothing'.
He discouraged the Opposition leader against plans to conduct a parallel ceremony when President Uhuru Kenyatta will be sworn-in on Tuesday.
The NASA fraternity has planned a memorial service for those who upon his return from the United States on November 17.
Uhuru will take an oath of office at Kasarani Stadium. Security has been beefed up for the occasion where dozens of global leaders are expected.
"The swearing in of a President is respected globally and if Raila will interrupt it, he deserves to be dealt with properly," he said at a church service.
"We owe him nothing in his twenty years of seeking the presidency. He should now spare us and retire in peace."
He said Kenyans have been rallying behind Raila since 1997 and hence he should let go of the claim to the presidency after the unsuccessful attempts.
The ODM leader lost the 1997, 2007, 2013, and later withdraw from the October 26 election after the Supreme Court ordered a repeat of the August 8 vote.
Kiprop said Raila has contributed to the democratic gains in the country and should now exit the scene in a honourable way.
He challenged the NASA leader to emulate him for conceding defeat to Governor Jackson Mandago during the August election.
"When I failed to secure Uasin Gishu governor seat, I supported Mandago," Kiprop said adding despite being out of office, he still feels he is a leader.
"I have been serving people several years back before I contested for governor. I will still do because I am a leader, " he said.
He added that the prolonged political season is costly for business.
"We encountered losses and therefore, cannot allow any individual to mess up with country's economy," Kiprop said.
