A local court had yesterday granted interim bail for a day to Revanth Reddy to attend his daughter's engagement ceremony.
The attendance of Naidu and several TDP leaders is seen as an expression of solidarity with the MLA.
TDP has alleged that the 'cash-for-vote' row and the video and audio tapes surfacing allegedly in connection with the issue is a conspiracy against the party by the ruling TRS in Telangana.
