The Orange Democratic Movement (ODM) has summoned ten leaders to face its disciplinary committee in October.
The party on Wednesday in a statement said the leaders would be expected to show course why they should not be disciplined.
It, however, did not give details on why they had been summoned.
Among those in the list is outspoken Malindi MP Aisha Jumwa, her Msambweni counterpart Suleiman Dori and Masira Duke Oyagi (Nyamira County Assembly Majority Leader).
Others are Nyamira MCAs George Morara Abuga, Damaris Nyarangi Muoni, Moses Abel Mokaya, Mogere Carolyne Gesare and Monica Mwamba.
Also in the list are MCAs Immaculate Joy Adhiambo (Busia) and Peter Palang'a (Nakuru County Assembly Minority Leader).
They will be expected to appear at Orange House on October, 10 to face the disciplinary committee led by Fred Athuok.
The communication comes about one and a half months after the party wrote letters to Aisha and Dori telling them to explain why they should not be punished for openly campaigning for Deputy President William Ruto who is from another party.
Aisha is yet to respond to the summons as only Dori has written to the party acknowledging receipt of the letter.
Aisha and Dori are among Coast leaders supporting Ruto's 2022 presidential bid.
