Mr Lubinda said in an interview that the protests by the youths in the ruling party in Lusaka were aimed at an individual and not any tribe as Mr Kabimba claimed.
Mr Kabimba has come under intense pressure from the party’s youths who are pressing for his resignation for allegedly harbouring ambitions of challenging President Michael Sata before the 2016 elections.
The secretary general, who is also Justice minister, has, however, reacted angrily to the protests and accused some senior party members of being tribal over the issue and sponsoring the youths to rise against him.
Mr Lubinda faced similar protests early this year before Mr Kabimba charged him with alleged treachery which ultimately led to his suspension although the cadres had called for an expulsion.
“When the protest was against me, he was in the forefront and nothing was said about tribalism,” said Mr Lubinda, who was hesitant to comment on the protests against Mr Kabimba.
“I wonder if that is tribal because as far as I am concerned, the protests are against an individual and not any tribe in Zambia, so he is in the better position to prove that the protests are tribal.”
The former Foreign Affairs minister said Mr Kabimba was an eloquent person who could easily prove to the nation that the demonstrations by some party structures were being sponsored by a tribal clique.
He said unless the party’s chief executive officer convinced the public that he was a tribe on his own, it would be difficult for people to believe that the demonstrations were sponsored by an ethnic grouping in PF.
Mr Kabimba said those wishing him out were just wasting their time because he would not go anywhere.
