Kirinyaga Governor Anne Waiguru on Sunday joined ODM leader Raila Odinga in the final day of Kibra campaigns ahead of Thursday's by-election.
Mr Odinga, who is rooting for election of Imran Okoth, has pitched in the city constituency for the last three days, meeting a host of communities.
On Saturday, Deputy President William Ruto who supports McDonald Mariga, laughed off at Odinga's campaigns, arguing that he's under siege.
Waiguru's presence at the final day compaigns is yet another strong indication of a looming alliance which could get spearheaded by Odinga ahead of 2022 polls.
Also present in ODM campaigns on Sunday is Makueni Governor Prof Kivutha Kibwana, who has been at loggerheads with Wiper leader Kalonzo Musyoka.
On Saturday, Kitui Governor Charity Ngilu and her Machakos counterpart Alfred Mutua met Mr Odinga before joining Kibra polls.
“We are here because we want Uhuru and Raila to show us the way in 2022 and nobody will come between them,” Mrs Ngilu said.
“Raila has done a lot for this country and he is the only person who will fight for the people of Kenya.”
Mutua said his party is in consultations with ODM on possibility of fielding candidates without much animosity to secure majority in parliament.
“My party will consult with ODM on how we will field candidates in the 2022 General Election so that we get the numbers to change this country,” he said.
On Saturday, ODM Secretary-General Edwin Sifuna repeated his earlier assertion that Nasa may be buried after the Kibra by-election.
“We have said this before, we are counting our friends in Kibra. New alliances will be forged from this by-election,” Mr Sifuna told the Sunday Nation.
