West Bengal Chief Minister Mamata Banerjee yesterday criticised the BJP's proposal of "one nation, one election", and said holding simultaneous election to Lok Sabha and state assemblies was not practical in a vast country like India. Agreeing that this could help keep a check on rising cost of conducting elections, Banerjee said the proposal was not practical.

"I agree too (on the expenses to hold polls). It (one nation, one election) may be applicable for local elections. But if you go for that and if tomorrow the central government falls then will the states and the central government go for another election. Please be practical," she said.
