ODM has fined Homa Bay Town MP Peter Kaluma and his rival Washington Ogada Sh100,000 each over chaos at the memorial of the late Otieno Kajwang'.
The two fought at Homa Bay Stadium where the event was being marked on November 27.
Kaluma was reportedly kicked, punched and wrestled to the ground by Ogaga in front of party leader Raila Odinga.
They were among seven party leaders summoned by the party's National Election Board to explain the cause of violence.
Others were Homa Bay Governor Cyprian Awiti, woman rep Gladys Wanga, Kaipsula Kanondo MP Oyugi Magwanga and Kevin Ouma.
They were accused of using youths to cause disturbance by heckling Awiti, as well as heckling and throwing stones at the Homa Bay Stadium.
"These activities have contravened the ODM Code of
Conduct, which they have pledged to uphold. They are also a threat to
the peaceful conduct of party primaries," ODM executive director Oduor Ong'wen said in a statement on Friday.
ODM banned Ouma from holding any elective or appointive party office over involvement in chaos.
"These actions should serve to convey a clear message to ODM politicians, aspirants and members that the party is committed to ensuring peace at its rallies and during party primaries," Ong'wen said.
