Sudi who had earlier left for Nairobi said he had sent his wives Ann and Lillian Sudi to pick up the document on his behalf.
Photos he posted on his social media pages showed his wives wearing smiles as they received the certificate before engaging in a short celebration with their husband's followers.
"Earlier today, I sent my lovely wives Lilian and Anne to pick up the election certificate on my behalf. I wish to thank the great people of Kapseret Constituency for giving me a chance to serve them in the National Assembly for the third time, " Sudi wrote on his Facebook page.
He added that he was committed to continuing serving his constituents with diligence, determination and hard work.
