He told reporters here today that the CWC decision is against the very principle of the state of Andhra Pradesh which was formed on the basis of the Telugu language in 1956.
The late prime minister Indira Gandhi had also opposed bifurcation in 1972 when people agitated for bifurcation of the state.
He said that Congress ministers and MPs failed to assess the situation in Delhi and were unable to restrain the CWC from taking such a "harsh" decision.
He appealed to all political parties to unite and fight for a "unified" state, besides demanding that all people's representatives resign from their posts to follow the people in the ongoing agitation against bifurcation.
Both Buddha Prasad and Devineni Nehru supported government employees for opposing bifurcation and demanding that people's representatives resign by August 12.
They also announced that they would participate in the movement to support the ongoing anti-bifurcation and anti-Telangana agitation.
