Even though, in "Reunion," Gowron offered K'ehleyr a seat on the Council if she backed his candidacy. But then, Gowron always was a hypocrite.
Yes, he was. He blamed other people (Martok) for his mistakes but never hesitated to come down hard on others who were merely being honest with him (Worf); if you ask me, the Klingon High Council was nothing more than a glorified good ole' boys network. That people could could challenge for the leadership of the Empire because they happened to be part of a certain bloodline (Toral being Duras' son, for instance) is proof of this.
