Kerala Chief Minister Pinarayi Vijayan on Monday lashed out at the BJP over the arrest of AAP leader and Delhi Deputy Chief Minister Manish Sisodia and said the Central agencies were being used to intimidate the opposition parties and termed it as an attack on democracy. Vijayan said the Centre was attempting to destabilize the opposition-ruled State governments in the country and termed it as a move to divert the attention from the issues of joblessness and economic crisis.
