I have this doubt but I'm also confident that TVK has full support from BJP, else it's not possible for any newcomer to party to win near majority seats.

BJP has done this in Andhra - Pawan Kalyan is now a bjp ally and before Pawan Kalyan Jagan was released from jail, given his own independent party to fight against Congress... Coz BJP knows very well that they can't win in Andhra... so create proxy parties
