Mr. Joseph all the people you quoted were behaving in selfish fashions, Seetharam Kesari-for PM post he destabilised governments, Karunakaran-ditched the party that stood behind him for CM post for him or his son, Natwar Singh-we know everything and as far as age is concerned, they were just expelled from the party not abused and physically thrown out of the office!! Neither Sonia Gandhi nor PM did abuse him personally, they just maintained that corruption is not bearable at any level and I think that is a welcome change for our Governments.
