Very quietly, a very important thing happened in the BJP on July 20 when L.K. Advani was not invited to participate in the NDA meeting although he has been its working chairman for a long time.
The cardinal mistake committed by Advani has been his failure to go by the dictum that a person should quit when others implore him not to quit. Instead he has willy nilly created a situation when many of his party members are wondering why he is not quitting.
