One person was killed and several others injured when strong winds destroyed tents during campaigns for JAP Kajiado Central MP candidate Patrick Tutui.
The tent reportedly fell on a crowd listening to a speech during the rally held by Deputy President William Ruto in Kajiado on Monday.
Police said those injured were rushed to Kajiado county hospital and the dead to Ngatata Health Centre mortuary.
Tutui will vie against ODM Candidate Elijah Memusi in the March 16 by-election.
Ruto will use the by-election to test his grip on the expansive Rift Valley constituency ahead of the 2017 general election.
He has camped in the constituency for the last two weeks, campaigning for Tutui.
Ruto is also set to test the waters for the proposed merger between his URP and President Uhuru Kenyatta’s TNA, even as he moves to reassure his support base of a stable relationship in the ruling Jubilee alliance.
His critics have questioned the rationale for the merger that will see the formation of a single political vehicle ahead of 2017, arguing it is a scheme to â€œuse and dumpâ€ him
