The situation escalated for the worse after Sonko began hurling insults at those who tried to cut short his speech and seemingly tried to attack one of the mourners.
The statement which he made in the presence of CORD leader Raila Odinga sparked laughter and shouts and temporarily brought the event to a halt.
It took the efforts of Ms Ndeti and other leaders to restrain the Nairobi gubernatorial aspirant who kept uttering unprintable abuses.
After some minutes of arguments and shoving, the event resumed with Mr Odinga and other opposition leaders in attendance steering clear of the drama and rather concentrated on assuring of unity with CORD coalition.
Ms Ndeti who is eyeing Machakos gubernatorial seat during the 2017 election lost her Nigerian husband two weeks ago after a long illness.
