"How can Left parties accept TMC in their proposed arrangement? TMC is totally opposed to our scheme of things," CPI veteran A B Bardhan told reporters after the party's two-day National Executive meeting ended here.
Though Mamata Banerjee's TMC was among non-Congress and non-BJP parties, Bardhan said CPI would never have any relationship with it.
Adopting a special resolution on West Bengal, the party's national executive alleged there was a sharp deterioration in law and order with offices of political parties vandalised and the police remaining silent.
"CPI national executive condemns lawlessness and undermining of the democratic public life," it said adding there was undermining of democratic liberty of political activists opposed to the ruling political establishment in West Bengal.
CPI asked the state government to restore law and order and ensure that law enforcement agencies acted according to the law.
