Umno secretary-general Tengku Adnan Tengku Mansor has rubbished Umno leader Khairuddin Abu Hassan's plan to lodge a report against the party with the Registrar of Societies (ROS).

He said both Khairuddin and his plan are "useless".

"That is what he claims (that Umno doesn't follow party rules). But is he really an Umno man? Khairuddin is useless (tak boleh pakai)," Tengku Adnan said snidely.
