Narc Party leader Martha Karua on Wednesday led Azimio supporters in Meru County in signing the petition seeking to oust President William Ruto from office.
Karua tweeted a video of residents appending their signatures and captioned it:
"Signature Collection from Muthaara Meru County."
In the video, a man is heard asking people if they are willing to sign the petition.
"Mmesema mnataka kusign? Mnataka kusign?" he asks, to which the crowd shouts in affirmation.
Karua was in the company of former Jubilee Secretary General Jeremiah Kioni.
Azimio leader Raila Odinga and his co-principals have asked Kenyans to take back their sovereign power through the signature collection exercise.
Addressing a Saba Saba rally at Kamukunji Grounds in Nairobi on Friday, Raila said the coalition targets 10 million signatures but on Monday, he upscaled the target to 15 million signatures.
On Tuesday, Raila launched a public website, Tumechoka digital platform, for the collection of signatures.
"This is part of the campaign of resistance, the civil disobedience and citizens’ actions that we have decided to pursue to force Ruto and his regime to respect and listen to the people," Raila said.
The signature collection process is however not among the legal ways in which a President can be removed from office.
The president can only be removed from office through parliament on grounds of impeachment or incapacity.
