Delegates of the United Democratic Front (UDF) on Monday endorsed the expulsion of senators Boni Khalwale and Martha Wangari from the party.
The National Delegates Conference (NDC) also approved the expulsion of suspended party chairman Hassan Osman and replaced him with Webuye MP Alfred Sambu.
Musalia Mudavadi remains the party leader, with former Kieni MP Jeremiah Kioni as his deputy.
The delegates also unanimously agreed to rebrand the party to Amani National Congress.
The delegates were forced to invoke the party’s constitution to call the meeting after some officials went to court to block an NDC that should have been held last Friday.
Mr Mudavadi was embroiled in a duel with Mr Osman, who was fighting his suspension. Mr Osman has been suspended on allegations of gross misconduct.
Mr Osman moved to the Political Parties Dispute Tribunal to challenge his suspension. He sought a moratorium on all party activities pending determination of the matter.
The Registrar of Political Parties, Ms Lucy Ndungโu, on Sunday said political parties could use Article 103 of the Constitution and Section 14 of the Political Parties Act to expel MPs, MCAs and party officials.
Ms Ndungโu said that once the internal party mechanisms had been used and her office notified, it only takes a few days for the decision to be upheld.
โPolitical parties can expel their members according to the laid-down procedure. They have their own internal mechanisms in their constitutions through which they can notify us,โ she said by phone.
Once this is done, such elected leaders lose their membership in the party and, in effect, cease to hold their elective positions.
