The party's National Elections Coordinating Committee (NECC) chairperson, Emily Awita, announced that the party was now ready to proceed with the elections, saying voting would take place in all centres in the 47 counties.
The NECC chair pointed out that there would be elections of 30 party officials, 10 each from the three committees at each polling unit or centre.
The Orange Democratic Movement (ODM) announced on Monday that it will resume its grassroots elections on November 27.
This follows the postponement of the polls in April due to flooding in most parts of the country.
