The resignation of Kalyan Singh

News like the one that reads, "Kalyan Singh quits BJP" makes one wonder as to what are the ethics and ideologies of a National Party. Veteran leaders quit parties saying that they have lost faith in the ideologies of the party. The 2 primary National parties in India are the Congress and the Bharatiya Janata Party. Over the past few years, both these parties have moved away from their core beliefs and ideologies. We have seen both these parties teaming up with parties that were at the opposite end in principles, just to form a government. We have also seen these parties compromise on their basic ethics multiple times, though nothing is yet proven (ah! what has proven till today).
This time round it was the turn of the BJP vice-president Mr.Kalyan Singh, to resign. This is the second time that he is doing this. Earlier he returned to the party after resigning in 1999. This time again Mr.Kalyan Singh went on to say, “I am not a bonded labour of the BJP”. He said that "OBCs constitute 50 per cent of the population, yet there is no honour and place for OBC leaders in the BJP."
These statements make one wonder as to what is it that Mr.Singh was expecting. I believe he wanted a special treatment just because he was an OBC. If this is not the reason there is no other reason, we can see, especially when Mr.Singh was serving the party as its Vice-President.
There is also a second story to it. Mr.Singh's son (the next generation politics) was yet to be seen on the forefront in the political arena. It was very unlikely that he would be pushed to the front or, given a ticket to contest the elections by the BJP. This meant that the political legacy was at a full-stop after Mr.Kalyan Singh. Mr. Singh saw a saviour in the Samajwadi Party, who agreed to give a ticket to his son, Mr. Rajvir Singh and for this to happen, he but obviously had to quit his party. What a move, Mr.Singh.
I wonder what is Samajwadi Party upto. It seems they are setting up a new business called politics.
