Amarinder Singh said today that he is not joining the BJP but definitely quitting the Congress, confirming speculation that had been swirling since he was forced to quit as Punjab Chief Minister, just four months before polls. "So far I am in the Congress but I will not remain in the Congress. I will not be treated in this manner," the Captain told NDTV in an exclusive interview a day after meeting with Union Home Minister Amit Shah. In a no-holds-barred interview, the Captain also said the Congress is going down in Punjab and called Navjot Singh Sidhu a "childish man" given a serious job by the party.
