The Jubilee Party has nominated Bina Tubi, daughter of the late Isiolo South MP Mohamed Tubi, as its candidate for the upcoming by-election, a move seen as a direct challenge to the United Democratic Alliance (UDA), which endorsed her brother, Tubi Mohamed Tubi, just weeks prior.

• Jubilee Secretary General Jeremiah Kioni presented the nomination certificate to Bina Tubi on Thursday, citing her late father's loyalty and commitment to the party and constituents.
• The by-election is scheduled for February 26, 2026, following the death of Isiolo South MP Mohamed Tubi on November 12, 2025, while receiving treatment at Nairobi Hospital.
• UDA Secretary General Hassan Omar Hassan had handed Bina's brother his nomination certificate two weeks before Jubilee's announcement, setting up a sibling rivalry for the parliamentary seat.
